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?
Indeed, you can not deny the fact that bitcoin and eth are safer to store than the new tokens you get for participating in bounty campaigns. But it all depends on what kind of tokens you got, from the market situation, what the price of this token is, etc. Each person chooses his own strategy, which is more suitable for him.
