IMO there are some issues with the model presented
So people buy at $10 per coin and are not able to sell until it reaches $100. Coins are only bought and price increases (pump) and once they get to $100 many will want to sell and price will go down (dump)...
"prevent sell" must mean the coin would be traded only on your platform (not cool)
There are only 5 coins over $100 (according to CMC at least) . None are stable coins. Ever wondered why ?
How will you ensure the coin will have a stable value ? Mint ? Are they backed by stacks of real $100 bills ? Will you buy tokens off the market ? Coins don't just "stay stable" you know...
If you have a better idea to avoid the crash, please share and we would be happy to consider it.
Your coin, your problem

To me it just sounds like OneCoin 2.0 stable version ...
