1.there are too many cryptos born in 2017
so natural selection must kill the non sense crypto ... and  a contraction is a "natural" evolutive process

2.some good projects will generate new cryptos (by fork or by intermediate service)
that will be more usable (as simple as paypal or a credit card), trusted and reliable

3. as in the past "ecommerce war" (remember ebay,amazon,google...) only few strong competitors will survive
and they will take all the market

 at that point investors that have in the stack the good currency will win the stackes
