Cryptocurrencies are software, they do not die. You invest because you believe the platform will gain use or that there is some underlying value in the held asset. The only way that a coin can die is if it is abandoned by the developers and is no longer traded on an exchange. The idea that 99% of coins will die is Bitcoin maximalist propaganda. They say this out of one side of their mouth while they are buying alts at low prices. Watch, in a couple months there will be another alt run and this propaganda will be ancient history.
