By the way, I had a similar situation as you in terms of my getting first involved in Bitcoin towards the top of a price rise (mine was the 2013 price rise), yet none of us can really know if we are at the top of the price rise when we are in the midst of it, but one of my advantages was that I was already in a position to be pretty aggressive for the next year - that started out as a 6 month authorization for buying/accumulating BTC and then expanded into a year... but surely it could be questionable about whether all my aggressiveness in buying in the first year of 2014 while the BTC price was falling had really put me in any kind of advantages place because aspects of my previously purchased BTC were largely in the negative for nearly 3 years with an average cost per BTC in the upper $500s in late 2014 that I was able to bring down to around $500 by the end of 2015.. but as we know the price of BTC had floated in the mid $200s for most of 2015. One of the advantages was that my persistence did start to pay off in late 2016 and for sure in 2017 and for sure, even the 85% price dip from the $19,666 BTC high in 2017, still did not come even close to less than 4x in profits for my overall BTC, and these days, I just like to round my overall cost per BTC to $1k per BTC to make calculations a bit easier, even though sometimes there could be various ways of accounting.. but if there is a profit cushion, then there is flexibility and less stress - both psychologically and financially.
Not only could we never know but for normies as I was and still am,,, we could never even know if there was going to be a rally or a cycle. Only 2 cycles had happened when I came and now I have the experience of living through one entire rally/winter cycle,,, I still cannot know for sure if this is another cycle or if we have a new paradigm of market behavior.
I am very happy to read it worked out for you and most importantly that you had the persistence to stick with it.
I read about others as old as you in this world but who gave up after the last rally thinking that was it
Initially, in late 2013, I had not known my investment target, exactly. I initially authorized myself a lump sum amount to spread out during my first 6 months investing, so I just took the amount and divided it by 26 weeks, and that was my allowance for each week. At the end of the 1st 6 months, I authorized myself to continue another 6 months with the same amount, and at the end of the 1st year, I thereby established my goal of getting 10% of my total investment portfolio into bitcoin....
I had already considered that I was not investing more than I could afford to lose because I had other investments and also I had all my expenses covered with my other monies and cashflow, but I did appreciate that my investment allocation was somewhat aggressive in terms of overall prudence of what regular people might consider.. but I still think that I always suggested that people who were less aggressive (or less of a believer) should allocate lower on the spectrum of maybe only 1%, so in that regard, I had always had some kind of recommendation that people should consider a 1% to 10% investment in bitcoin in terms of all of their investments, and surely since late 2013 (or even since late 2017) the investment thesis for bitcoin has gotten a quite a bit stronger in terms of likelihood for success. of course, the upside potential is likely NOT as great as it had been with a lower price, but the solidness of the investment thesis got better in terms of how various governments had been reacting (up until then or up until now) and also in terms of other ongoing developments and surely the resolution of the 2017 fork wars in terms of attack vectors against bitcoin had been fairly clearly resolved in favor of bitcoin.
Furthermore, even these days, there is nothing really strongly taking away from bitcoin's investment thesis in spite of some hostilities from China, but there are other bullish factors including El Salvador adoption, other countries considering similar measures, and some of the onboarding of pretty BIG players and financial institutions. so there always have been negative information in the mix, but that negative information should really be informing guys/normies in terms of how much to invest into bitcoin (whether taking a 1% allocation, or a 10% allocation or some other amount), not whether to invest into bitcoin.
Surely, some people choose not to invest in bitcoin at all, which surely is a mistake that a lot of people make by considering 1) how much and 2) whether as if they were the same question... kinds of all or nothing thinking that does not really serve the individual interests in terms of there is always going to be risks to any investment or ways of allocating value whether in bitcoin or some other investment(s) - even though bitcoin still remains amongst the best of investments that is still available out there... whether others recognize and appreciate such ongoing upside potential or not.
