On Smoke.io members who achieved 50,000SMOKE POWER unlock the slider. The slider allows you to define at what percentage you upsmoke posts.
If you are technically inclined, you could always use the CLI_wallet and upsmoke directly from the wallet. When using CLI_wallet, or any similar tool, you can define the percentage at which you upsmoke.
