Coins like BTC and ETH have proven beyond reasonable doubts that they are the best and more safer coins to invest. My little advice is that, whenever you get your altcoins, it would be better to convert at least one third to either BTC or ETH to serve as some form of insurance to your tokens in case it fails to survive. I used to keep all my altcoins and now that the market is red it has badly affected my investment. And mind you, those new altcoins are not like BTC and ETH, they can get zero volume anytime so they are not reliable. Is there any other person with a different view or everybody agrees with me?
I prefer to exchange my bounty token into Ethereum but of course not all of them. I choose one or two of them make some experiment for me personally. It really is a price will be bigger in the future for it. In most cases this does not work, but I believe that one of them will be great.
