I think the Bitcoin transaction time is 10 minutes per post. But to make sure that your Bitcoin account will avoid the block is to make sure that your time interval is range from 30 to 45 minutes in every post that will you make. You must remember that when your Bitcoin account is block, it is hard to get it back. As a simple reminder, make a post in every 30 to 45 minutes to avoid blocking you Bitcoin account. And last, make a table of time for you to assure that you follow the correct interval time of posting in Bitcoin.
You misunderstood something here. I don't know what you mean by "post". There are no "posts" in Bitcoin network. I thought you might be talking about posting on this forum, but you said transaction time so that makes no sense. Also there is are no time intervals defined in the Bitcoin blockchain, it is just mathematical puzzles that are likely to be guessed by the network on average with 10 minutes of guessing. These puzzles are readjusted every 2016 blocks to adjust to the current guessing speed of the network.
Some people refer to Bitcoin addresses as accounts, so I guess that is what you are talking about. There are no blocks on your address. You can send whatever amount of transactions you want and your address will never be blocked by the network. Anyone can make as many addresses as they want as well in a fraction of a second. Blocks aren't necessary since you pay a fee for every transaction to be included in the blockchain.
You also don't need to do anything every 30 or 45 minutes or anything like that. Neither on the network nor on this forum.
