Do you agree that more people will choose to invest in bitcoins if there were not so many cryptocurrency choices although not all are good?
Yes yes.
It's like when you are in a class and you're the most intelligent, you will surely be at the top. Same with cryptocurrency. Bitcoin is at the top in terms of market cap, and it's the most trusted cryptocurrency that's why people will still prefer buying it than other altcoins out there.
Bitcoin being the most trusted cryptocurrency is enough statement already. 95% or maybe 97% of the altcoins are just pure crap and can't be trusted at all. Bitcoin will still be the #1 choice of investors.
