The thing about mining is that it is not the most trust worthy way to invest your money. The amount of companies that are considered legit to mine your bitcoins is very low, most of them are fraud. Genesis mining is one of the old companies and is obviously legit. But legit doesn’t rhyme with profitable. With the rising price of bitcoins it’s very hard to understand what profit means in mining, and how to get it. People mostly use these king of marketing techniques to steal you bitcoins.
