Comparing crypto and Blockchain is like comparing apples with oranges

Bitcoin is the digital token, and blockchain is the ledger that keeps track of who owns the digital tokens.
Blockchain has a better future than cryptos because crypto is a part of Blockchain
The difference is the same which is there between bank databases, money and dollar.
 
consider.

Bitcoin is Dollar
Cryptocurrency is Money
Blockchain as Bank Database

You buy and sell using dollars. What it actually is to you is money. Each of your transaction is stored in a bank database.
Many Industries have already started using Blockchain to keep a track of all thier records. while many countries are still not sure about crypto currency hence manybe crypto will die and Blockchain will survive.
