problem is, allot of those miners won't get ROI for many months. Knowing this, I would expect most (except for those who took out loans) to choose to wait for higher prices before getting their fiat back.
Exactly, I dont see why on this forums people seem to think that miners want to get ROI as soon as possible. I think 90% of them will just mine and hoard, for years
Well, if the price gets high, it would make sense to sell to lock in profits. But if that's what people were doing, the bubble would not have been quite so crazy.
I'm sure you know the bubble started more or less when block reward halved, which was a moment when nobody had ASICs yet, 99% of the network were GPU and FPGA miners... Those already had their rigs paid off long ago (no new GPU and FPGA miners for a while because everybody was expecting ASICs since last summer), so as soon as they saw their proceeds halved they started to hold like mofos, creating scarcity of coins, which made the price to grow - the growing price attracted speculators, speculators bought driving the price high, the media started to run stories about how Bitcoin price was growing, which attracted more speculators, etc... Wash rinse and repeat, speculative bubble in its purest form.
This cycle is about to invert when ASICs will be widespread. Same thing happened in 2011 with GPUS.
You really think people took loans to buy ASICs? I bet you most asic owners are early adopters from GPU times.
I surely don't know what's the %, but I surely know there are a lot of newcomers spending all their fiat savings (tens of k's of $) in miners because they think they will break even in one month and then they will have a x10 ROI in the first year... Loan or no loan I don't know, but you can be sure they are throwing at this more money they can afford to lose because they think this is a "no brainer" and they do not want to "miss the train".
I know for sure because I've been meeting/discussing with a lot of guys like that since March, both in cyber and meatspace.
There will be a lot of pain for miners very soon, you will see.
