What crypto-currency have wallet on phone ?
A real one -with backup & restore & official support ... not a backdoor to a VIRTUAL wallet hosted on exchange.

ALTS are good to trade and it's an hoover for FIAT money (good, because Bitcoin is the last step after trading ALTS).

Bitcoin is a vault for 100 years.
