At least, the project is alive thanks to the continuous support of the community. It won't be able to gain traction, but it'll be able to stand the test of time. RSK serves as an alternative smart contract platform for those seeking unmatched security reliability. Since RSK is a Bitcoin sidechain, it's much more secure than other existing platforms such as Ethereum and Cardano. If developers want the project to succeed, they're going to have to ramp up their marketing/promotion efforts. Otherwise, it'll slowly fade into oblivion as other projects gain all of the attention from people in the mainstream world.
To my surprise, two small projects have been working with the RSK sidechain. It's not much, but at least it's something. Whenever they'll benefit RSK in the long run or not, it's yet to be determined. With fierce competition in the crypto/Blockchain space, it's hard to believe RSK will gain traction in the future. Yet, anything could happen in this strange and bizarre world of crypto. As long as RSK remains decentralized, there should be nothing to worry about. Just my opinion
