does anybody really feel that it will go back to 1200$ (practically)
If it doesn't go astronomically past that point, it is a fail that will just disappear.
This is correct. Longterm, the price per coin and market cap must continue increasing with difficulty or the incentive system would fall apart because btc wouldn't be profitable to mine.
I think bitcoin will sail past 12,000 United States promissory bancnotes. Transparent decentralized mathematics vs. The full faith and credit of a military empire currently sliding into collapse and economic ruin...
This isn't that hard to predict. No hegemony in history lasts forever.
If BTC becomes unprofitable to mine, then people will stop mining it. Then difficulty will plummet. Then it becomes profitable to mine again. The system is not so fragile.
