Agreed, if they were going to accept crpyto it would much more likely be BTC,LTC or *Cringe* BCH. TRX is just an ERC 20 token right now and is held by speculators, not well known to the general public at all.
That said, I think TRX will probably go up quite a bit still. The hype around the coin is quite big, it is a pity for them that they are launching at the same time as EOS as they will now be competing for market share for pre-launch pumps.
The point that I would refuse to enter a position is probably around 1200 sats.. for now I think TRX is still buyable if you are willing to sit through a few days of possible red.
