On this term, I advise you to invest in ETH and hold coins until the end of next year. I think next year will be better than this.
Yes, If you are in search of altcoin to invest in and hold for a year, I think you should invest in ethereum because it is the best and most potential, valuable coin and also good for hold on long or short term. You can also invest in EOS, NEO or lietcoin, they are also god coin and also good for hold. Stay calm and just keep hodling mate.
