What coins do you suggest for long-term holding? Bitcoin and Ethereum excluded.
I think the coin is suitable for long-term investment besides ETH and BTC is NEO. NEO has a solid foundation and great potential, hope you will follow my advice and buy NEO today.
NEO and ETH is the old altcoin, why not try the new one? like EOS, TRX, ADA,... They have strong communication
besides Bitcoin with Ethereum, there is Ripple as a very good coin to use in length.
with its ever-evolving ability to make Ripple highly reliable in the future as a very lucrative main coin. so I recommend using Ripple for the long term.
