Nice tips you got there but I think your tips are lacking something. One of the most common mistake a newbie does is to invest in only one coin which in the end leads to loss if that certain coin does not perform well. That being said, you should have had included there this: "diversify your investments. Never invest in one coin only and always remember to not put all your eggs in one basket".
How if the money of a newbie are small and it's for only in one coin, how they can split in to different cryptos? Lol
By the way that's right if you decide to invest in crypto the better way to gain more profits are spread your money in difference coin just in case and it's a great tips in a lot of members in forum and most of them in newbies.
