How do you define a crash of the mining market? If you mean that hashrate will implode, fat chance . IF you mean that mining hardware sales will dry up, well, think about the consequence of that. If indeed hardly anyone were to buy miners anymore, the one thing that will surely happen is that prices will plummet, considering most mining asics are still sold at the very least 10x above marginal production cost Clearly vendors would prefer to sell at 5x, 3x, 2x marginal cost over barely selling anything at all.  And if prices plummet, miners will buy again. Its this very mechanism, a spiral of death of exploding difficulty and plummeting prices that caused this, what you call bubble (and what I warned you against if you remember). Its not stopping anytime soon.
