What I am going to write now is a bold statement but I honestly believe that if you do a a little bit of research and invest into lets say top 100 coins and hold it for long term you will most likely make money.
I believe we are in the age of cryptocurrencies. You almost can't go wrong especially if you invest in the top few coins since everything about cryptocurrencies is new and fresh and alot of population doesnt even know anything about cryptocurrencies so there's a lot of room for growth.
Perfect moment to invest as much as you can to be ahead of everyone else.
I think you made a good choice :-)
