Sure, but you are not forced to use shitcoins. There will naturally be some cryptocurrencies that are worse than others, just as there are FIAT currencies worse than others (e.g. Venezuelan Bolivar vs the Swiss Franc). Consumers being given a greater choice offers opportunity for them to choose to use currencies with superior qualities than the ones they would otherwise have access to. Like with other choices in life generally, the consumer has a responsibility to make an informed choice. While failing to do so has adverse effects for the consumer, it is not the fault of the currency that the consumer made an uninformed or poor choice, no?
