The point about being only rich on spreadsheets is right though - there is no true profit until you sell out of your investment. Up until that point it's essentially all hypothetical - it's not like it's a FIAT investment with a fixed value, it's only worth what the current price and if you sell.
On bounties, I definitely think there is a case of projects using bounty hunters to further their message without offering much in return...but this has always been the case and really is the whole point is it not? The difference is just that in 2020 there are more projects/increased competition and the market isn't as healthy vs 2017. Supply and demand = less profit in bounty hunting.
