The offer is probably too high to even be turned down and with the bull run almost at the front door, its pretty much a good decision to sell it for all for btc then wait until the bull run comes knocking the market
This probably a second thought for @devans since he's already said that the burden of responsibility of managing Bustabit is going to be shaky in his hands currently. I do agree though that it's a good decision, if I'm in the same position and I have already a pretty good profit out of my business and someone offers me something that's really difficult to refuse and in exchange I would be relinquishing the management of a profitable business but I can afford to be on vacation in a year in any tropical country of my choosing? I'd definitely be taking that offer.
