I had fears too but now hope, I invested a big amount in crypto market, i was new in September 2017 and first I invested little amount then i seen it gone down and i got my amount at loss price but after 1 week i again seen it goes to high and high everyday and that time i was new in crypto then i felt guilty that why i sell my amount at loss price...after sometime i again thought to put a huge amount and i did in January and after that crypto market fluctuations started and i seen 3-4 times it goes up and down but it never gone to that price at which i put and after that i still hoping hoping and remains only hopes.
