There's a cryptocurrency called RaiBlocks that is working to be the best at transfer of value. The protocol uses new cryptocurrency concepts evolved over the years and I believe it can be quite revolutionary. In my opinion, bitcoin is one of the worst cryptocurrencies at the moment, and to be honest I hope to see it die soon.

Create a wallet using this site https://raiwallet.com/, paste your address here and I'll send you some raiblocks. The transaction time is about ~5 seconds and there are no fees, so it's almost on par with a credit card, except you don't depend on a bank or a credit card company.

Also, check out this link to google trends: https://trends.google.com/trends/explore?q=raiblocks. You'll see that the country with the most interest in raiblocks is Venezuela, which coincidentally is going through hyperinflation. Bitcoins used to be quite big there as a way of avoiding the loss in value of the national currency, but as the country became poorer and the cryptocurrency networks more congested, the fees became prohibitively expensive. Raiblocks could be a good alternative to cash, or at least help some of the most technically savvy people.

What I'm aiming at is, give the technology a chance. As the top poster says, it might be a big bubble, but it might also be a revolutionary technology (or both, just like the internet).

EDIT: Sorry folks I have to go so you'll have to wait until I check my account again. Still I'll do my best to keep sending as long as people keep asking.
