I think you should have a lot of research where you can make a profitable investment in a short time and a long time, so you will more easily get many benefits, and you can invest now in bitcoin, eth, Ada and BCH.
I also agree with you, you should study and read more about the altcoin you are aiming for, and I recommend you learn about ETH and NEO.These are altcoin that can bring high profits in the future.
