Oh i think its always best when they allow for altcoin investments and not just the big 2-3. Even if they have to use a third party convertor that accepts altcoins and they get btc/eth, being able to invest third party coins that we have in a project is a great incentive for buyers.
Thats right. There are some altcoins with lower fees. Or some kind of preference to Eth and BTC. Also, some fist options without any restriction should be available.
