Add to your top fives bitcore. It's all time high reached $40+ and now it's currently $2, if you are good enough on finding gems in the crypto market you'll get this notice.
While it is cheaper today, start buying it as we all believe that the bullish market is about to come soon so while it isn't here yet get some already.
I wouldn't recommend you anything aside from bitcoin and ethereum. It will be a bad move if you don't want to invest your money in this two because these are the best coin to invest in that will surely satisfy you to a big earnings. You can buy right now since the market is low so that soon that it will rise then you can have a big money.
