The reason we use the sidechain in the way that we do is actually to circumvent even more fees. Remember, that the website that you use is only a means of simplifying smart contract interaction, at the end of the day the bread and butter of Morpher is its smart contract protocol.
Keeping Morpher on our own sidechain allows us to distribute virtual ethereum to users, which is used to pay the fees associated with the smart contract calls. Since it's on the sidechain, we can produce this virtual ethereum, and send it to users regularly (that's why you have 1 ETH in your sidechain wallets). Unfortunately, this does necessitate users to keep their MPH on the sidechain when they want to trade, and thus move it to and from the mainchain - incurring more fees.
This is an inconvenience, but it allows the trades (contract interactions) to go fast and to be free for our users. The trade-off is transacting to and from the sidechain and paying the high gas fees of Ethereum.
If you would rather trade exclusively on the mainchain, this will soon be possible, and if you're crypto savvy and want to help us test a few things feel free to reach out to me. However, mainchain trading will be different. You will pay the gas for smart contract interactions on every trade.
CoinNar Are you going to keep your silence on this subject? Or will you find a real solution?
Switching blockchains is not a solution. The solution comes in making Morpher more retail friendly. We already support on-site deposits that allow you to skip having to buy MPH on an exchange, allowing you to buy tokens with Paypal or payment cards. It's not a perfect system, and not all countries are supported, but we are adding more deposit methods that should cover more countries. The next logical step is to have some sort of fiat-offramp, direct withdrawals into fiat. This is also something that we have in our pipeline.
