This is you just backing out of the argument. I would love to get into specifics. Btw I am not heavily invested in bitcoin. I have a few but even if the bullish prediction of the vinklevii comes true it won't really change my life.
I am however massively excited about the possibilities provided by cryptocurrencies.
You know I don't have to subscribe to bitcoin as the winning ledger (yes, ledger not protocol) to believe in cryptos.
ok you've got my intention there, this suggest that you have most of the issues figured out, how do you think we will solve:
1-The Block size limit when the number of transaction/minute is 100 times higher than today.
2-The block chain size when it exceeds 200GB or 1TB ? most users or services will have to use clusters of storage, if the adoption rate picks up this has to be fixed really fast.

running a bitcoin node consume so much resources (bandwidth consumption and memory, mempool containing unspent Txid) how do you think a normal user will have to deal with these issues, he will have to use centralized wallets and services which against the fundamentals that Bitcoin was created for in the first place.
3-The energy waste, it has been known that when the price goes up mining becomes more profitable and more resources are brought online...resources that most of us consider wasted, as of today the hashrate is more that 250 Petahash/s, assuming that the worst chip on the network consume 0.5w/ghs (which is way too optimistic) this means that at this point miners consume way more than 125 hourly Megawatts... just FYI a typical nuclear plant produce from 500-2000 hourly Megawatts.
4-DDOS attacks: when Bitcoin become bigger, there will be Big services that run the Bitcoind in order to offer their services, organized groups can run denial of service attacks against these services, you can read more about how they can do it in that wiki I provided before.
5-Malleability issue, and don't tell me it is not an issue, because it really is, and it is not fixed yet, they just found some work around it.
6-Double Spending, even if you don't have 51% of the network you can perform double spending with as little as 25% of the network,
and this did happen before7- The 51% attack, we all know what it is, it is achievable, any government can achieve it if they want to kill Bitcoin, even at this point.
8-man in the middle or packet sniffing, also described in that wiki.
There many more issues, but these are the one that concerns me for now. now I would like to hear your solutions.
