Yes, this is very relevant.
It took me some time to finally crack this. If you think this riddle is hard to solve, imagine not having any hints, for the clues I'm giving you nearly solve the riddle, entirely.
"XBT had a Twin Brother, XIC; but the latter will murder his brother, in cold blood, and rob him of his crown and all his glory. The wicked Twin, rising from the sea - who will ruthlessly enslave and rule the world, is marked and will be recognized by all, according to his evil mark and number."
I'll leave it to everyone else to solve this fairly simple riddle. And please don't bother with all the 666 rhetoric, this is gonna require a bit more thinking, but it's there.
In solving this riddle you are likely to find the keys to great fortune; albeit, holding on to that fortune will prove a much greater and painful challenge.
I'm going with BTC and XLM.
I have no justification for the XLM choice, but I haven't seen any mentions through my minimal exploration
Stellar is an up and comer for sure.
