Are you talking about a cryptocurrency that could be listed on an exchange? Or just a token usable on the site only. Because in case it's about a crypto I see a problem in. Let"s says the token triple or more within months, the company will so start to see reduced profits and so losing money.
These are really good questions. In fact, I've asked them to myself and the rest of the team a number of times. Below is what we have came up with that helped us to solidify the use of blockchain for our solution.
First, we want to utilize blockchain's ability to gather consensus from all users for marketing purposes on an immutable and transparent ledger. Nodis.io allows businesses to post up Challenges for people to participate and receive crypto as reward. Upon completion of a Challenge, participant will submit the proof (image, video, etc) on our website for validation. This is where blockchain comes in. We will open up to all users on our platform to validate the submissions. Majority side of the voters will receive a small portion of tokens as reward for the effort. All votes will be tracked and recorded for transparency. This community validation process will give businesses significantly more exposure. The best part of all is that this whole process can be automated. All businesses have to do is post a Challenge and done. This can potentially solve the lack of time issue. And when participants/voters are paid in crypto, it'll resolve the lack of money issue. The only cost is that businesses are required to post up discount vouchers for exchange with tokens.
As for the token pricing fluctuation issue, that's truly a tough one. We will be listing on an exchange as we are looking to do token sale. Our current option is to have a fiat-to-token conversion calculator so that people know how much token to pay for each voucher.
I hope these explanation helps!
