Not the amount of knowledge of bitcoin will cause its collapse. The only thing to knock down here is the demand. If there is no demand and pure negative news that the events are happening it may have fallen.
So do not be afraid because many support bitcoins.
Seriously, bitcoin cannot go down for that reason. It is already given that there are places which internet connection/modern technology is not accessible so it is also understandable that bitcoin and cryptos are not known in there. Even if we really want bitcoin to be used in the whole world, with the case above, we cannot achieve 100%. Anyways, bitcoin is still doing fine even if not all people are able to use computer and know about bitcoin. Yes its price is on dump but dumps like these are common in here and this is just the volatility acting up.
We don't have to be pressured achieving that 100% because bitcoin will still be able to recover, succeed and maybe surpassed the $20 000 peak price last year. The population might help in increasing the demand but it may also result to more people knowing bitcoin but do not know what to really do with it.
