Looking at the rapid growth the Croptocurrency world is experiencing right now, with new and promising Tokens (ONL, ATFS, BERRY etc) being introduced on regarly basis. I actually have a strong confidence that cryptocurrencies would get worldwide acceptance in the nearest future, and with Bitcoins topping the charts of all existing Bitcoins right now, Bitcoins stands to benefit from the newborn cryptos emerging. So if you ask me, I think it is quite impossible for Bitcoin to CRASH.
No i dont fear I dont have holdings of bitcoin. I have altcoins maybe if i will see the chart moving upward i will trade some of my altcoins to bitcoin. Not sure though. Sometimes it is more profitable to invest in altcoins but not all altcoins are trustworthy, a lot also are garbages.
