but if we look at the market there are lots of people buying altcoins, and to be honest I also like to buy altcoins but there aren't many of them, and it's still my biggest investment in bitcoin. and to be honest even though investing in altcoins is risky but I always want to buy and the reason is because of the high pumping..
The human nature to have greed run their function is common and this is why gambling industry works and also why rugpulls and shitcoins run well. I not implying that every altcoin is a scam, but most of the newly launched ones are going to be such in a couple of years or less.
Making money from altcoin and making money from bitcoin, I would always go with the second one because that carries less anxiety and less loss of sleep. As a trader you need to limit the pressure you put on yourself to stay healthy and trade.
