True... for now he just said that the technology is "pretty neat" and what it provides is "good to be true" and that he bought some.

But as far as I know he never promoted any other coin other than BTC and Litecoin, even less a coin that is a direct competitor to Litecoin... Also the fact that he made his own research before doing this tweet shows that he is serious about it.

Will he ignore NANO for now on, or focus equally on Litecoin and NANO even though they are competitor or move to NANO ... that it still to be seen.
