It good to diversify one's investment but choosing your investment through the rank on the capital market or via technical analysis doesn't mean the coin is a good investment saying this cause I don't think DigiByte is a good investment although it a forked coin of BTC and it has been in existence for long but I don't trust the coin and I believe holding your BTC is a better decision now.
Since it has 5 algo and can't be easily 51% attack, which part you don't trust?
