currently the number of existing virtual currency reaches 1400. Bitcoin is not the only virtual currency in circulation. there is ethereum, ripple, bitcoin cash, cardano, NEM, litecoin, and so on. But bitcoin is one of the largest virtual currency market capitalization.

I think we should support bitcoin or altcoin, but not all altcoin, now very much altcoin and most of them are useless for now, we can save some of them for use as an alternative to Bitcoin.

I strongly agree that many people support more than one coin. but with 'support' I mean by supporting a new coin-coin whose prospects are good to make new coins useful and useful.
