Bitcoin (BTC) is currently undergoing parabolic growth in the setting of unprecedented institutional and retail demand. The market cap is currently US$287.6 billion on US$22 billion worldwide volume over the past 24 hours. The market cap is approaching that of a major bank, such as JP Morgan and Bank of America.

The entire Bitcoin ecosystem, including the network and all exchanges, has been under heavy load over the past week, stress testing the network's ability to scale.

The network’s mempool, or the number of unconfirmed transactions, has increased to levels not seen since mid-November and is currently over 200,000. The all time high for backlogged transactions was over 225,000 in May 2017.

As more and more transactions are piling up a higher fee must be used in order to send a transaction with higher priority. As the number of pending transactions subsides, miners work from the top down, accepting transactions that paid the highest fee first. Transactions are never lost but may take longer than expected when an appropriate fee is not paid. The current best fee, as estimated by btc.com, is a median of ~$10/260 bait.

Unlike November, block times have remained unaffected and currently stand at ~9.5 minutes. The block size is now averaging just under 1.2MB. With more exchanges and wallets enabling SegWit addresses every week, block sizes will continue to increase and more transactions will be confirmed per day. SegWit transactions are now ~11% of the total.

PPL can't spend money now - bcs most of transactions not confirmed - so it can back to account the was sent - so we lost this money - thats the problem

To not cry about order limit -check ur payments at blockchain first to see has it to be confirmed yet or not

PPL who send with hight fee (0.0000046 BTC / 1 byte) and not heavy transaction (250-300 byte / 0.00138 BTC ) get money fast and can spend money here

This transaction for example not confirmed yet: https://blockchain.info/ru/tx/f7aa6558b92e3892e7e9f82ceee18b4b224b9e39ba266fe949f07b2c7cb618ee

His commission is: $ 3.34
Size of transaction: 226 byte

Right commission: 0.0000046BTC x 226 byte = 0.0010396 (Its about 15.32$ by Poloniex.com rate)

So if anyone will ask about limit - permanent ban
