this is just obvious. why would anyone choose something that could fall apart any time after they buy it? or knowing very well that it is controlled by someone and he has noting he could do about it.
Bitcoin proves again and again to be the mother of all crypto and yet we are here talking about buying alts. I don't know about you and your vision but for me it will always be Bitcoin.
For investment goals that achieve large and quick returns, people prefer alternative currencies over Bitcoin. Even most of those who prefer Bitcoin are long-term investors and very few use it for daily transactions.
Personally, I always prefer the less risky options since I am not an investor. The same reason prompts me to use usdt to freeze my balance while bitcoin price drops. Of course, the usdt currency is also considered an alternative currency, but it is less dangerous in times of falling bitcoin prices and the rest of the major currencies.
In my own opinion I will say that why people prefer investing in altcoin than bitcoin it is because altcoin will be buy or purchase in low price why bitcoin will be purchasing higher price but during a bullish market when altcoin rise you will have a more dollar and altcoin investment if the altcoins can survive a bearish market.
