At present the price of OmiseGo is $3.96 another the price of Lisk is $3.90. It almost the same price.
Do you know whose future value will go better?
This is a stupid way to evaluate an asset. There are several differences between these two projects: total supplay, its functions, its roadmap, its yield.
We are not talking about two products. You should never invest like you are buying apples at a fair. Same price does not exist. If it were for this logic, buying NANO would be much better since it is costing less than half. But it is exactly the opposite.
Now, about the projects. OMG has a gorgeous roadmap. It is one of the projects with greater potential that is not a currency or platform. That is, it does not compete directly with BTC or ETH. You can live with these other giants. It has practical use in commerce and already has use cases. It has already hit almost $ 20 a few months before.
Lisk is already a platform. It has had its governance seriously compromised and needs radical changes. Compete with platforms that today are much better as ETH and Cardano ADA.
I would choose OMG.
