Payment to SNO in Etherium

For a Noob like me it’s very confusing as I know nothing of wallets, tokens, ETH or blockchain.

I’ve sold shares in the past with no need to deposit the fees in advance. The postage stamp is a good analogy though.

Just been reading this > Best way to exchange STORJ with BTC and ETH each month?

All told it sounds like an initial small payment in ETH would be very helpful.
