To save the NEO I recommend you to use Binance. Binance as well all know is a fast growing exchange for buying/selling cryptocurrencies from anywhere in the world. Binance exchange also has numerous inbuilt wallets for HODLing different cryptocurrencies but there is a special thing about NEO wallet of Binance.The NEO wallet of Binance also gives you access to the NeoGAS tokens on the 2nd of each month which is not done by any exchange wallet so far now.Thats why HOLDing your NEO in Binances NEO wallet is highly rewarding unlike keeping it on other exchanges. Not only save you can also buy NEO in Binance.
