I'm bullish for Ren in medium term, there is no direct competitor to Ren in the market atm.
Ren can bridge Btc into Cosmos ecosystem, bridge Dot and Cosmos while other projects focus on liquidity by atomic swapping such as: uniswap, kyber, thorchain, synx - these projects are purely about trading pairs. If you need your btc to execute or pay a smartcontract then this is the case for Ren
