Right now, should be a good time to realize that if you really want to buy bitcoin then you should be careful about it, otherwise you are not going to get anything done and it will be much worse of you if you are not careful about it. I get that some people will want to make it work as much as they possibly could, but that doesn't mean that it will be enough. Bitcoin is something that gains momentum very quickly, when it goes up, it doesn't take years for it to go up, like how it takes years for it to go down.
I don't know what you mean by very careful though, the price is going up we can understand that, but still it's a good price to enter as we all know that next year we will be having a great run, reaching new all time high. Maybe in the 6 digits are most of us predicted.
So, you should be very quick with the trigger if you want to get in at the right time. I believe we have a very short window of opportunity right now and if we are late then we may still profit but a lot less because we got in too late. So, we should be making some money when we have the time, and it could definitely be something that would worth a lot of money and time as well, we need to make it work in order to keep it growing even bigger than this.
Look for long term investment in Bitcoin and it you could be good in my opinion. Just like last year, if we pull the trigger and bought at $15,500 last year, then looking at the price today, more than 150% profit? That is already huge.
