which bitcoin needs to be upgraded in my opinion better in wallet security, transactions, and have a guaranteed profit on development so can depress the negative side in people's view if they want to invest in bitcoin no doubt

if I get a bounty token then I prefer the first because there are times when not many people are selling their tokens and that's why harha tokens will go up (for bounty tokens of high value)
I sell (low value tokens) to exchange to ethereum for me to sell by turning it around for little profit but repeatedly

this will make it easier to exchange currency values
my opinion for cryptocurrency in the future will be more advanced because if we travel to a country that has its own crypto currency we are not difficult in exchanging money for the purposes there
so if all countries launch their own crypto then it is not impossible if crypto will become world currency.
