When a project is coming in market with some real use case which will benefit uses the the early entry gives huge profit. Bit we need to recognise the potential in early stage. Altcoins are profitable but not as secure as bitcoin as they are controlled by team. I don't keep altcoins for years except the coin has extreme potential.
Simple thing to me, Make money from alts by trading in short term and convert it into btc and hold for long term.
how do you know there will be a coin with extreme potential? while altcoins have not been able to balance BTC in terms of the market, alcoins with extreme potential are only predictive so the margin of error is also large, both TRX and BNB they are still captivated by the ups and downs of BTC
