There will be a conversion rate, but it won't happen till after the presale sell off.
I'm going to reserve 3,000,000 of these coins.
18,000,000 sold off in the pre-sale and 3,000,000 in the conversion.
Each of these new coins would be worth .0001 or 10k sats.
I'm going to put the price of a single DoScoin at 166 sats. So about 60 coins per the new coin.
60:1
Of course, you will be able to buy into increments up to .0001 of the coin.
