If youre looking to make money through trades then why limit it to just crypto? If anything, diversifying would be much better. There are sites like eToro (as well as others) that have a copy trade system. You find your account with a certain figure and then set parameters as well as the people you want to follow and your account automatically emulates their trades (buying and selling).
Realistically speaking though, nobody is going to trust a group of readers. If its not an official site/Company then nobody will invest...
Of course you should diversify. However, most copy trading platforms do not have cryptos. eToro could be an option.
