As long as people aren't scared off from buying and hodl'ing.

You have to pay for security and encryption hardware to keep your crypto safe in cold storage.

But you also have to pay for an RFID blocking wallet to keep your credit and debit cards safe when you go shopping in the high street.

You have to hope that your wallet doesn't physically get lost or stolen and your cash and cards are taken.

You have to hope that your Dow/FTSE/Nasdaq/Nikkei share portfolio goes up, and not down. Or that companies you invested in go bust. Or there is a crash in the market.

You have to hope that your bank doesn't go bust (especially if you are over the FSCS protection value).

What I am trying to say is that people shouldn't be scared of cold storage of crypto. There is a risk to everything - even fiat currency and "normal" methods of investment - and you should balance your own risk.
