Not everyone likes crypto. Sometimes you can change their mind sometimes not. Luckily I was able to and since then I've had a ton of altcoins. My favorite one at the moment is KuCoin.
For those who don't like crypto, that person doesn't need to be ignored because crypto doesn't need people who have negative thoughts, so just show the results to people who don't like crypto, so they see that crypto can give good results and not lie.
