I've checked a number of factoid slots and found some points that might find interesting to discuss with you.
I'd like to discuss some of the points I quote below about the future of bitcoin, and I'd really like to know if you're worried about that?
1. Remember that Bitcoin is still beta software. Don't put all of your money into BTC!
2. "I'm sure that in 20 years there will either be very large transaction volume or no volume." -- Satoshi
About the first point: I assume that there is a risk of failure on this currency given that bitcoin is still beta software. I don't know if my concern about that is unreasonable or not, but there are certainly risks I can think of.
About the second point: It is possible that there was no transaction volume in bitcoin's first 20 years. However I wouldn't worry too much about that because up to now the volume of bitcoin has been huge and bitcoin has dominated the market for a long time.
Then, what do you think about the two points above.
I don't really have any doubts regarding the bitcoin network nor its existence will be in the next 20 years, bitcoin will stay and there is no flaw in the network.
But my only concern is bitcoin will remain as speculative asset forever so we only talk about bearish and bullish trends, what will happen to the price, what is the right time to invest???
Because it is created to be used as a currency which part is still not happening in the reality, 99% of the bitcoins are used for trading and investment purposes.
