I think Cardano (ADA) is a good coin for holder.
Cardano aims to integrate with all other major cryptocurrencies without the use of a third party, which:
1. Reduces fees that exchanges charge
2. Allow quicker and easier transactions across the blockchain
3. Removes risk of a third party losing your cryptocurrencies
Cardano is a good investment for the above reasons and the fact that it has only been on the markets since October.
