One of the main unique selling points of btc is now massive liability, and has been for years.
Its rendered btc useless for most commerce transactions, as the majority of transactions made in business are small
I don't really know how true is this claim
But it is certainly not the primary reason why Bitcoin is mostly useless for commerce right now. It may play a certain role of course, but it is surely not the most important one. After all, merchants could just open their checking accounts in any reputable and reliable web wallet out there like Xapo or Coinbase and then start receiving payments to these wallets off-chain (from other such wallets), and thus break free from limitations imposed by high and higher transaction fees (if they were really interested in accepting Bitcoin as a means of payment in the first place)
