Bitcoin’s Mempool, or the measure of transactions waiting for confirmation or “payment completion”, has been increasing steadily over the last few months and is at very high levels since the end of 2016.
Mempool or “traffic jam” information for the Bitcoin blockchain is publicly available at the blockchain.info website and gives information on how likely it is that transactions in bitcoins may suffer a delay.
The extent of possible delays in Bitcoin has already resulted in other Crypto coins like Litecoin, Ethereum or Dash to gain more attention by worldwide Crypto coin users and merchants. Both groups are likely to suffer when payments are delayed and will be looking for better, as in faster, solutions for transmitting payments. This has already given a number of the more popular Alt coins significant price moves because of better expectations of future mass adoption.
Delays in Bitcoin payments can also be avoided by adding higher transaction fees to payments and gaining priority over other waiting transactions this way. Recommended fees are increasingly over 100 satoshis per Byte. Figuring out and using the correct fee for payments in Bitcoin is unpopular though and not likely to be used by most regular users.
