Bitcoin !CryptoCurrencies ! My Struggle Continues..

Bitcoin the Crypto Currency started fascinated me last year around Nov 2017 when the prices of the same were skyrocketing close to $13000.The rise in prices were so prominent that I started reading more & researching more about crypto currencies.

Then came the term blockchain technology...And as I read more about the same it made me believe that this is the Future & will begin new mass revolution & adoption.I tried to understand blockchain, the backbone of bitcoin but fully cound not understand it.I still struggle today to explain block chain.Can anyone explain me ?

Fascinated by Bitcoin I heard of Bitcoing GPU Mining Rig, the hardware required for it & the process of setting up a bitcoin miner.Day & Night i watched youtube videos of people explaining about the bitcoin miners & the hash rate per GPU to mine the bitcoins.It made me so excited that I invested $1200 in building a mining rig.I started to mine ethereum,mined it for a week then stopped it. I stopped it as I didn't find it profitable & it some killed my craze.Did you guys invested in a miner ?At that time bitcoin was trading around$10000.

Now Bitcoin trading below $8000, I read posts on steemit which claim it will reach$10000,I really hope so it does.But Before that I have one question do you guys really believe in crypto currencies & if so why?
