Lol. Just because it is still standing, doesn't mean that it isn't a shitcoin or will never fail. Lol.
Okay pal, let me give you some advice, instead of focusing on investing money, try to invest more time on learning. I suggest that you go and try to research more then study as much as you can about crypto currencies and how they work so you can get a grasp on what to look at to be able to make the right investments and  to be well equipped to differentiate worthy investments from non worthy investments. Yes, I know it sounds so tasking and very tiring, but believe me man, it will absolutely be worth it. The knowledge you will gain will both be your weapon and shield while venturing through the harsh world of crypto currencies. Having the right knowledge you will be more sure with your decisions without having the need to rely on other people's suggestions. After all that is your money that you are investing and not anyone else's. The only one that will benefit from all the profits and the only one who will lose money is you. I hope you'd really think about this deeply.
