I'm right around $12k for the month, I started the month (Dec 4th) with around $1000.
I was going to put $5000 into IOTA, but just let it ride with $500 once it started to move and sold early which gave me almost 4x return, I was in Ripple at .19 as well, but not as much as I should have been. XVG helped a lot, but I don't believe in it much so I sold a 75% when it was on a big run, which in turn paid for a large amount of VEN which is gonna carry me through the year and allow me to make more daring moves.
My advice is to get something that is in the .01 - .20 range or even lower than a penny, that way you can buy a ton of them for less and if it takes off you can sell and parlay that into another move. If you research something follow your gut, I've passed on plenty of things that others have told me were gonna flop only to see them rise, so read up everything you can on a coin, check the charts & market cap.
I dabbled in crypto before, but I got really serious with it in the last month and half, I'm trying to get enough money to invest in a friends business which I feel is going to be huge.
