What about a hard wallet for holding? i always think about this for holding long term
Yes. Cold storages are the best way.
Iām happy with coinbase instead of 2 or more crypto wallets. It helps me exchange bitcoin, litecoin, ethereum, and other cryptos that I donāt need to look around for any other option.
OK but i don`t like online wallets. 
Cold storage is the best if you ask me. No worry there about the security. There are brokers who offer cold storages. Google few and maybe youāll find your fit.
Cold storages yes but brokers who offer cold storagesā¦ that must be some invention.
