Today when it comes to domaining, undoubtedly, crypto-currencies domain names are the hottest investment avenues. This fact has been substantiated with the very recent sale of ETH.com. The Dot com names are always best. Since there is only one dot com per entity, the non-dot com domain names become the second-best alternative.
I Googled and found the following relevant sites topping the results for crypto terms:
