Damn. I must be living under a rock. I bought some NEO on Bittrex a couple of days ago. I kept it on Bittrex too. What's this GAS claim? Being a noob sucks.
Gas is generated for holding NEO. GAS has its own price too.
If you are going to hold NEO for a long time. Then it is much better to store it on NEON wallet for you to receive the GAS
