I really wonder that why ICOs are open to buy with crypto. Is it the way of demand generation??
I think it is just employed to create a healthy relationship between btc, litecoin, etherum, and other altcoins because it gives different personalities the opportunity to purchase in their ico the type of altcoin they hodl or own.
Similar, i think most icos , make good use of ETH, BTC AND LITECOIN, WHILE SOME ENGAGE WITH OVER 15 ALTCOINS TOO.
do trade typically.
