i have a feeling that most of altcoins' future depend on btc as btc is the face of crytocurrencies at the moment.
This is correct but at he same time while some altcoins are worth your investment, altcoins have a problem, if bitcoin begins to do badly then it is likely they are going to do badly as well but if bitcoin begins to do well as it is doing now then altcoins are not going to be able to grow as fast as bitcoin.
