What coins do you suggest for long-term holding? Bitcoin and Ethereum excluded.
I suggest you buy and hold NEO and Monero. These are very promising altcoin. NEO is called the Asian dragon, it was born in China, NEO has the technology and direction is quite similar to Ethereum. I believe in the future NEO will grow and compete with Ethereum. Monero offers privacy, every transaction with Monero is completely anonymous. No third party can find the Monero user information.
In the crypto market, there are many potential coins and worth holding. Truly, everyone has their own thought or trust to the coin that they feel good for investing in or holding. Only with the coin you choose and believe, you realize how much potential it can show. I am holding some coins, one of them is Neo and I kind of trust on it. Its technology is great, yep probably Neo compete with ethereum. Ive heard so many people appreciate Neo, and with what I had observed I think Neo will be a prospective coin.
