Prior to the Lightning protocol and even before the New Year started, Bitcoin introduced a radically new proofing system called #PROOFOFWAIT.
"When you spend 20,000 a piece for a digital currency, you're clearly interested enough to wait some days for it," is the unannouced message a look at https://blockchain.info/unconfirmed-transactions tells you. To reach the impressive waiting times, Bitcoin replaced the increase of blocksize by an increase of mempoolsize (https://charts.bitcointicker.co/#mempoolsize)
The measure is also a precaution against unresponsible people who might want to convert Bitcoin in also currencies. Their aims stay: unconfirmed!
Don't get nervous when you see hashtags like #BITCOINISBROKEN. Just: stand in line and WAIT.
