There is little difference in earnings whether you go solo or start in a pool:
- Solo: When you go solo you are your own master. Staking is required and could take a while depending on the amount of GRC you have in your wallet.
- GRCPool: Pool fees are minimal. No staking required and you will be paid on regular basis. You don't need to buy GRC when you use this option. Once you have gained sufficient GRC you can go solo.
You don't need to create a team, you can just use one user name on all systems. You can manage a group of systems both solo and in the pool:
- Solo: I would suggest to use the account manager BAM! in BOINC, which allows you to manage all your systems in BOINCStats.
- GRCPool: You can use the GRCPool account manager and manage all your systems in one of the menus on the website.
Hope this answers you questions.
