People want to become profitable from cryptocurrency. Some people want secure their fund cause it needs to take higher risk for higher gain that's why btc is good to be hold. Might be give you Small profit but safe. And altcoins are risky. altcoins will give you much profit. A multiple time higher than bitcoin and that's why people jump to altcoin investment but they should keep it in mind that altcoins can trun into shitcoin anytime. So make diversification, buy both btc and good altcoins for best deal
And who wouldn't be? This is the point of all of this on why we are here. It is because when we have more money we can do almost anything that we wanted to and that somehow eases the stress and problems that we feel. Taking higher risks and at the same time securing a fund seems contradictory to each other.
Even if it's only low risks but once we invest it, it means our funds are not totally secured anymore due to the volatility and other factors but no doubt that BTC is a good choice here in crypto. I think any coins including BTC can turn into a shitcoin once a very unfortunate event happens. So indeed that diversification, not only in cryptos might help us save some of our capital.
