I think you either have to get someone who thinks donating 10 BLURT to people they don't know will improve BLURT to the point that the amount of BLURT power they have will appreciate more than the loss of all of that BLURT they spend on account creation. Otherwise it is reliance on altruism.
I think a credit card option would make things more accessible for most of us. As for cryptocurrencies, there are like six top coins that are used the most. I'd say these are BTC, BCH, LTC, Ethereum stablecoins, DASH, and DOGE.
If you know anything though, you're not going to use Ethereum or BTC network to buy something selling for 10 BLURT worth. Doing so is like sending a SWIFT transaction to buy a hamburger. The fees are out of alignment for that kind of thing. That leaves four.
Why, it's a clever little leprechaun!
Good points made.
One thought... is 10 BLURT the lowest we can go? Is there any way to start up basic accounts for, say, 5 BLURT? Or maybe there's a way to do it essentially for free, as with Hive's system. The only amount needed for each new account would be the initial amount in its wallet (so they can make their first posts/comments).
