It's a beautiful sunny morning on the December 21st 2017, i open Blockfolio and WOW! $1,000 in profits from the different currencies I have 'tried' out. All through the day I think of all the things I could use my profits on (holiday, downpayment for a BIKE etc).
Fast forward to 5 pm, profits down to $700 (still no worries), by 11pm am down $500, to add to my worries i had transferred BTC to try and buy in on an ALT coin, 8 hours down the line the transaction is still pending and I have missed the buy-in I wanted. It's 2 am profits still down, transaction still pending, i go to sleep.
I wake up to a bloodbath on the crypoverse, everything is just red, in 24 hrs BTC is down almost $4k taking down with it most of the ALT coins. I check the steemitke discord group and one 
I remember my first crypto correction around 2014/2015, I panicked and sent about 0.1 BTC to the wrong address and another 0.3 BTC went down with the exchange I was using then. I was left with so little I gave up on crypto. There is a lot of panic at the moment and I learnt the hard way what it can do, and what it can cost, so nowadays am a HODLER!!!
I don't know why the price of BTC plummeted over a 24 hr period but a bit of humour may be a whale somewhere cashed out to buy an island or a small country as a Christmas present (we may never know). I have to share this, the guy below killed it hands down!!

My take in all of this:
- Invest ONLY what you can afford to loose, greed is a vice that doesn't end well.
- Understand that the crypto market/blockchain is still new and very volatile tread carefully, learn as much as you can by yourself don''t always rely on what you hear on the WWW.
- Tether (USDT) only lost about 2% of it's value (light bulb).
As always i choose to remain steemed-up!
