Hi there, I'm new to altcoins. Anyone has some usefull tips? Or a strategy that worked for you? 
Hey i see that you are new so lets me explain. Altcoins are like coins but they are made after bitcoin the main coin. Investing in altcoins is a smart thing to do many people have made a lot of money.
I know a friend that holded a altcoin for a few years and then the price went up he sold them all. He made money for patience actually.
