bitcoin and alt coin are both related to each other.
I support both because I think eating without drinking will not be complete.
Bitcoin and altcoin is a Crypto currency.So even you can inverse in bitcoin or in altcoin.Its nasser on your wish.Since altcoin is best for long term profit.I will support altcions.
bitcoin will continue to run without altcoin, but will run stagnant and even down, altcoin plays an important role in long-term business expansion, the more the number of crypto ecosystems will make the system more complex.
This can be seen from the variations of existing trading volume, altcoin can not be underestimated because it is the best choice when the bitcoin market is experiencing a downward trend.
