I recommend a few BTCL2 testnets/tasks that you can play recently. Because they are on the testnet, there is almost no cost. If you have time, you can participate.
1. Bsquared
There are currently points tasks that you can participate in.

2. Merlin Chain
L2, promoted by the Blue Box project, currently has the most powerful layer of assets. The testnet has just been opened for a short period of time, but the project team has previously said that the testnet itself will not have token airdrops (I guess other incentives are not excluded)

3.BEVM
It is an L2 project launched relatively early, and the ecology is gradually improving, so you can participate.

Tutorial: The first phase of the Odyssey is over. It is currently the second phase. Just follow the tasks.
There is another one that is set up by nodes and has a certain threshold.

4. SatoshiVM
The project token has been launched and has rapidly risen from more than 10 million US dollars to 150 million US dollars before falling back to 30 million US dollars. It's currently quite controversial, so the priority can be lower. The test network is also quite busy, with more than 300,000 addresses. Currently, the official plan to launch 5,000 NFTs to reward test network users. Decide whether to participate based on your own energy.
