In my opinion, trading in the order of coins 10–20 will be very risky, and there is no guarantee of profit. It will only make you depressed because the capital you have is divided among the many altcoins in circulation. It is better for you to buy coins in order 5–10, and after that, you can save or wait until the price goes up. Usually, this doesn't require a long process. Bitcoin, Ethereum, and BNB still remain my best choices.
Yeah good opinion, trading in top 10 coins is better.
I have used bitcoin , Ethereum, BNB, ripple and Solana.
But BTC, ETH, BNB are my favourite coins for trading.
Trading always has risks, if we want to do in low risk, we can be a holder.
But it requires a long time and free funds.
People say cold money.
I do both, trading and holding.
