Advise please. What is a good wallet for a charity to use in order to accept cryptos?

There seem to be a few alt-coins offerings that are specifically aimed at the charity sector, AIDCOIN and GIFTCOIN are two that I am aware of. I'm not quite sure what the point is, as why no accept a coin that is universal?

I set up a wallet with https://cryptopay.me (link includes referral code :)) for us to accept BTC. I personally use Coinbase, but I am curious what the Steemit community think.

What would be the recommended method for charities to accept cryptos?

Thanks!
