Re: Block Chain question

If I send some bitcoins to some address, and I pay the proper fees, how sure am I that it will be included in the next block? Are there any guarantees if I want my payment to be included in the next block that is mined?

Actually just pay recommend fees you can get your transaction sent less than 10minutes. Guaranteed Wink

is there no limit to the number of transactions in a block? what if everybody pays recommended fees? so some will still not make it? am i right?

Then it will depend on priority[1]. Technically, if everyone pays the recommend fees, those with higher priority or higher coin age, input amounts, fees and lower transaction size will get into the block till it's filled. The miner would still have the final say however.
