I don't know any sure fire way easy ways to make money. My friend works in crypto and seems to make good money that way; however, it is super competitive and like any small business it requires a lot of blood, sweat, and tears. It is not for everyone and it definitely not easy.
The thing i am doing is looking for companies, who are doing loss leader type deals to get new investors or customers in the door. For example, a coin called Tapcoin-Hooch (Hooch is their platform) is offering 300 dollars in credits to sign up for their platform, which gives you 31 days of free drinks, free food, and access to extremely reduced hotel stays all over the U.S (plus other countries). You also get VIP access to special events and classes. So, basically, they are paying you to sign up for their service for free and giving you free stuff to do it. I will post other sites and examples as i think of them. However, these are the deal you need to look for. it is hooch.co i believe. You need to be sort of a hustler and think of your feet. If finding these deals were easy everyone would do it.
