Let me offer another point of view to @socky's emphasis on exchanges.

Take Litecoin, for example, it is noted that Coinbase moved 25% of the circulating supply to their cold storage.

Think about that for a minute and understand why that coin is being pushed heavily for adoption. In this world, if you can't sell your product, you lose.

Coinbase literally has too much ridiculous of a stake to want LTC to fail on them.
