Most legitimate companies have more to lose than to gain by disappearing, because of a variety of reasons, the most important one being accountability. Im not yet convinced you could be held accountable if you decide to run one day. But here is a thought, again based on escrow: put a non trivial BTC amount in escrow, to be released to you after x months, or to be used to compensate victims if you turn out to be a scam. In the line of business you're in, you should be able to afford more than a symbolic amount for this.
