It's not a Bitcoin problem.
..is hard to imagine impact for new users. but for majority of them them, it looks like this:
* downloaded and installed some wallet
* somehow more or less secured their wallet, read lot of stuff about it, how to backup it, etc
* created and
verified exchange account, wait 1-2 days
* transfered fiat to exchange, wait 2 days at least
* bought BTC at market price
* initiated transfer from exchange to their wallet
and now, they have to
wait another bloody 1 or 2 days, even they somewhere read, that it takes ~10 minutes in average. believe or not, but they are not aware about stress tests, blockchain site or amount of confirmations. their VERY FIRST experience is, that they have to wait in
really uncomfortable situation (because of no experience, they are scared that money/BTC are lost), for endless hours.
sorry, but I can't agree with you. it is bitcoin problem and it is quite huge one...
