Although the forecasts of these experts are not always 100% correct, I understand that the simple fact that a youtube channel with millions of views suggests that the price of a cryptocurrency is going to rise...it is almost certain that it will rise at least for a few hours after the video is published.
I consider better strategy to invest in these coins than for example in coins with more liquidity but it is very difficult to make a x10 ... especially having the option to put a stop loss to limit possible losses ... what do you think?
Investing in coins that YouTube channels talk about is a bad idea. No, it's a terrible idea. No normal investor would ever invest in a project just because someone on their blog said it's a really good coin. The main point of these blogs, where they share signals about promising coins, is for you to buy these coins and make liquidity to those who have already bought these coins. It's a kind of version of the old Pump-and-Dump scheme, only using famous bloggers.
Real x100 coins no one will ever reveal until they need to be heavily propagated. People think bloggers help make money, when in fact they are trying to make money off their audience.
