it's hard to be able to banned the new altcoin because of the ICO, CROWDFUND and AIRDROP. These are the new coins that come out this year. If other people are confused about choosing or investing in their coin we are no longer guilty of learning about crypto. my opinion is that I favor new coin appearing because of the opportunity that is just a pretty good background of the company and increasing the bitcoin exposure to other exchanger this possibility will still be in bitcoin. Today I do not see anything wrong with tokens that appear to be wrong to us if we choose the right coin. Another coin is just a bait to raise funds for us to make it worse when we get into it. so we make our own research before we invest.
