Bitcoin is always better than altcoin investment. But trading should not depend on only one coin.
As a trader, wherever you're good at with these pairs, you can depend on those. Whether it's only for Bitcoin or any other coin or one coin, just keep what you've started. Some could have been good with USDT pairs and Bitcoin and some are the other type.
Those who have good capital to invest should diversify their funds. Although there are many good altcoins among altcoins such as BNB Ethereum.
I do agree with what you've said. When we invest, we have to make it happen that if we're only focusing on some altcoins then you better diversify and choose to have Bitcoin as well. But remember that not every diversification is a must.
The only way to increase your chances of making significant profits is to trade alternative coins that offer better altcoins. But since Altcoins are very risky, you must be careful with your trades.
Nah, you can make better profits by just simply holding bitcoin. But since the topic is all about trading, that's the other way around if you have good experience in trading other altcoins.
