Also how much has each rollbot price has gotten since it was first launched? I'm quite certain that there are users from this forum who also invested to Rollbit's Rollbot.
I did buy both of them during the presale though. The V1 presale was $500 each and V2 sale was $1000 each and as for the current price of each both, that would have to depend on the traits of the bots. Most common bots ended up way below the sale price right now but anything that is considered as good traits should be selling like atleast 3 times the presale price
