Was wondering how long u guys mine with your hardware.
I'd guess the really proffessional, big miners buy as soon as its released and sell them further after few weeks, and get themself the new stuff then.
The big problem is you can get a little profit doing this and flipping on ebay. BUT if you get a bad buyer that uses it for a few weeks or month even then wins a paypal dispute you lose big money. People on this board are smart enough to buy direct.... so hard to sell for a markup on most miners.
I sold a R1 a month later person went to paypal said it was not a reliable wireless router.... yes the R1 is a cheap router all buyers should know this going in. Yes it is not great to use as router if your wanting one to connect to and get internet on multiple devices. But almost a month later I got the R1 back and had to give him his money back. People exploit paypal on miner... it is sad but some do it.
I like buying and keeping for a while. I normally keep till it's a generation old and my ROI math makes me think I can sell and make more then mining. And in some cases it is a good amount more selling. So I keep my gear quite a while in most cases.
