Yes, I know.. but I cannot understand how it is possible to exchange them on Etherdelta..

But it is currently exchanged on EtherDelta... so are people selling/buying tokens? How is this possible?

Thank you

I also tried to transfer GRX to another MEW, with gas 200.000 and 250.000, but it fails.
Any suggestion?

I know that... the problem is that I cannot see anything in Myetherwallet.
The problems seems to be the ETH address where I sent my ETH: 0x701512a4343d590aa830227624bff515ce7cc871
If you try to search such an address now, I can find only my 0.15ETH received
It actually seems a wrong address... can someone check? is that address correct?

I have just sent 0.15ETH to the address listed in the Buy Section:
0x701512a4343d590aa830227624bff515ce7cc871

but it seems that something went wrong. I cannot see my tokens in my wallet..
