1. Open the Unisat wallet and switch to the Fractal Bitcoin Testnet network in the upper right corner. You can then go to the off-site store to buy test water, which is very cheap, about 0.2U per tFB test water. Of course, you can also go to get water yourself, 0.1tFB each time, and the same IP can be repeated every 6 hours.

2. Then, get 2 to 5 test_sats tokens. Each token requires about 0.01 tFB test water. Remember to keep some test water. Don’t use it all here. You will need it later in the "Tutorial from Sparks".

4. After the transfer inscription is engraved, you can make a Deposit. The subsequent withdrawals, swaps, and point cards are not available yet. We can make a Deposit first. Of course, we can also do Pools later, which is our group pool. It is not available yet and will be opened later.

Summary: Type-based Bit is a very popular project with zero cost. It is recommended that you participate in it. You may not gain anything by doing it, but you will definitely gain nothing by not doing it.
