Well, I think this is where services like BitPay is not helping at the moment. {Converting BTC directly to fiat}
The merchant that accepted BTC should not be able to convert ALL the BTC it received, INSTANTLY back to fiat. {I know they do offer the merchant the option to choose, what percentage they want to instantly convert to fiat}
Let's say BitPay or any other payment processor agree with merchants, that it would hodl the coins, until a 1% to 3% increase in the value occur and then sell it, then we would see some short term rise in the price...or even better, if they can hoard it for a longer period, until the price increase.
Yes, this is price manipulation....but it's being done will all commodities, eg. {Oil / Corn / Gold etc. etc...} ....so why must Bitcoin be any different?
True, what you suggested will increase the holding time and make those coins disappear from exchange for even longer time, and my use case just showed that even BitPay instantly convert the BTC into fiat, the bitcoin that used for transaction would still be occupied during the transition phase, which is 3 hour maximum, and 1 hour minimum. During this time frame the bitcoins for that specific transaction were not available on exchanges
In MV=PQ formula, V (money turn over times per year) is 0.05 when you hold coins for 20 years as a retirement fund, and it is 365 when you spend coins once a day, in my use case it is 365x8=2920 (8 times per day, and 365 times per year) for a immediate transaction. Then M is 21 million, Q is world GDP at 75 trillion, then you get a P of 1223 dollar per bitcoin if bitcoin is used every 3 hours, and 8x that value if used once a day, and 96x of that value if used once a year
