No one tries to store value for a couple years... On a ten year horizon, Im sure it will not decrease. I agree with some of your sentiment, but its not going to zero. That time has passed. It is a volatile as it is a new asset class. If you were trying to make a quick buck, you should have been buying in 2022 and 2023. Any memecoin can go to zero at any moment. BTC cannot go to zero at any moment or to put it more accurately, its as likely to go to zero as gold is. BTC is less likely to go to zero than USD is. The debt in the US and BRICS are legitimate threats to USD.
I definitely agree that people should only invest what they could afford. This goes for any investing. You shouldnt be trying to get rich quick. Its been almost 5 years for me and Im only now starting to get my head above water. Its not easy watching your money go to 50% of its previous value. If you understand what you are investing in it makes it easier.
