I prefer more to have neo and gain gas from it.
The neon wallet is also a great one to have and its NEP-5 technology
The speed is really fast anda cheap in gas.
Technology wise NEO is ahead, but this two coin is actually good to hold for long term. I also used NEO before and its really fast but we need to diversified our investment and these top altcoins have the chance to reach the peak, same thing with ETH so grab that two coins now.
