RC is a function of SP. If you have sufficient SP like to 20 to 30 SP you can manage your daily activity smoothly. In the following ways, you can recharge your RC immediately.
Resource Credits is what replaced the bandwidth that the Steem blockchain. The Steem blockchain recently hard forked to version 20.0 of Steem the software about 3 months ago. This new upgrade removed the bandwidth system and replaced it with a new system called resource credits. This new system has caused some confusion among many Steem users since they weren’t able to post in steemit.
so when ever you run out of resource credit and you want to post on steemit or any other steemit D-apps, you just have to recharge your Rc or get your RC up. so in order to post on steemit or D-apps , you have to get more resource credit through the following;
1. buying of steem power
2. waiting until your resource credit recharges
3. Holding more steem power increases your resources credit
4. waiting until network usage decreses
i hope this information is useful
Basically you can either wait to recharge, or buy more Steem Power to have more RC (Resource Credits).
You can see how much RC (Resource Credits) you have and how much is your current RC (Resource Credits) recharge rate on the following link: https://steemd.com/@groynes
According to Steemd, you currently (2018.12.24, 14:33 CET) have 25.50% (1.1M /4.3M) RC (Resource Credits). 100% recharged in 3 days. Your recharge rate is 0.86M per day.
Well the usual thing many people do is to wait for the resource credit to recharge back automatically after few days..
But i believe the best action to take when you have exhausted your resource credits and you want to urgently comment on steemit is that you
should power up your steem wallet and your resource credits will increase and allow you to comment and the amount of resource credits you have will determine how many comments you can make....
