I can’t say about other coins, but Bitcoins are really looking good at the current price.
Currently Bitcoins are at a best price, where you can buy ample of Bitcoins. Once Bitcoins start gaining it’s pace, it won’t stop until it reaches it’s all time high price.
So if you don’t want to regret later, then buy as many Bitcoins as you can. This is my just a small piece of advise. Rest is up to you.
