So if I have a good understanding about the inherent expansion in value because of the limited supply of bitcoin, and the fact that countries are using and even legalizing Bitcoin as it filters into more societies and exchanges, is it the last chance to buy cheap or at least affordable bitcoins?
cheap, you thought very well and you already know that the price will rise over time, I do not understand why you want to know if now is the time to buy cheap coins,
if the price today were $5000 would you find it too high or would you find it too low?
and if in December next year the price is $12.000?
if you bought for 5000 $ then you will tell the people that you bought very cheap.
it all depends on your purpose, how much profit you get when buying bitcoins
Will they cost 10k by December 15-20k next year?
as I said before, you know that the price will rise, now you want to know if the price will reach more than $10,000 next year?
russia and some countries can legalize bitcoin until December of the next year, maybe many billionaires use bitcoin, so the bitcoin price will not be the same
be patient and avoid creating high expectations
Or do we have more time to collect them at cheaper rates?
This depends on your objective, is possible to fall to $3500 until November, do not take my opinion as financial advice.
