Hey, do not beat yourself up. Carryout an assessment of everything that has happened and go back and re-strategize. It's not too late to get rich via bitcoin. Go to your crypto-friends and speak with them. Since they are your friends, talk to them. You never can tell they may be nice enough to borrow you their one of their device to help you get back on your feet.
Well, I did read through the whole thread, and it does seem that several of us question the extent to which OP might be telling the truth in terms of what had happen to him in terms of whether the alleged facts really add up and even whether the course forward ends up being rational or reasonable at all - even though for sure, many of us recognize and appreciate that people can frequently NOT be rational or reasonable in their balancing of their finances and/or their psychology when it comes to something like bitcoin.
Of course, if OP had been into bitcoin since about 2010, we would have presumed that he would have had some smarts to himself when it comes to technological matters..because there were likely not as many user-friendly ways to get into bitcoin back in 2010 as compared to the various ways that any of us might get into bitcoin today.
Another confusing angle is the OPs choice of "crypto" in terms of describing his experience, and who the fuck knows what is crypto.. He seems to be talking about bitcoin, and I have some difficulties mentally processing why any genuine person who had got into bitcoin in 2010-ish would be so damned confused about what the fuck bitcoin is to refer to it as "crypto" - even though I know that vague-ass denigrating term "crypto" does exist in the wild and a lot of forum members, including a lot of members participating in this thread choose to parrot such term - including even some folks who seem dumb (or is it gambling-derranged?) enough to be recommending that OP identify some shitcoin and get into that as an investment with potentially better UPside potential... seemingly going into unit bias presumptions regarding shitcoins having value based on their unit price.. so sure maybe OP would be receptive to getting into some nonsense pump and dump since that seems to be the way that OP had treated his bitcoin investment in terms of failing/refusing to see it as a long term investment in which he should have been setting some coins aside anyhow... so how would anyone with any kind of appreciation of what bitcoin was/is actually be left with ONLY 15 bitcoin after having been in bitcoin for 5 years at that time in 2015.. and sure I can see it happening.. but I am being critical of non-introspection.
The more solid of the recommendations forward in this thread did have to do with suggesting that OP get back on the horse, and to learn from his past mistakes, and whether that is possible with OP or not, it seems to be a decent talking point in terms of anyone who might be reading this thread.. and that has to do with anyone having trepidations about bitcoin, refusal to stay invested into bitcoin and to walk away, they are likely going to have fun staying poor if they do not grow the fuck up sooner rather than later... In other words, bitcoin is likely serving as our greatest wealth transfer in history, and if anyone has doubts about these parameters (presumptions), then it would be a matter of how much they should invest into bitcoin rather than whether to invest into bitcoin. .. and fuck shitcoins, they are not part of the greatest wealth transfer in history, even though they are sucking off of bitcoin's teet along the way.. .. so in essence, you gotta figure out how much to put into bitcoin 1% to 25% of your investment portfolio, and the overwhelming majority of any "crypto" portion should be into bitcoin, such as 90% and if you want to fuck around with shitcoins with less than 10% of your crypto investment then that would be acceptable, even though 10% invested into shitcoins would seem high...
There are also some devil into the details about how to get started in investing into bitcoin. I used to suggest people to try to invest at least $10 per week, but in recent times, largely since March 2020, I have been suggesting $100 per week.. but of course, each person has to figure out their budget, and surely there are some folks who can ONLY do $10 per week.. and so after a decent amount of time of investing into bitcoin of perhaps a couple of years, the BTC portfolio may well start to feel as if it is getting sufficiently larger and more options come as the BTC portfolio grows.. and another aspect is that it best that investments into bitcoin have a 4-10 year or longer timeline.. . and of course, you can still invest with shorter timelines, but some of the parameters might need to change.. and even the expectations of being in profits are not going to be as clear with shorter timelines of less than 4 years...
Sure, more could be said to OP.. but just giving some ideas.. and walking away.. if that's what you did seems pretty lame.. even though I do know that people do walk away from bitcoin by failing/refusing to get in, but with OP at least there is some experience, but he still likely has a lot to learn, and part of the learning is getting back in and establishing a reasonable, prudent and personally tailored approach. .and then putting such approach into practice...sooner rather than later.
