Isn't it good time to rethink on our decisions? In Dec17 BTC was all time high and its just few months back, now the current price is around $7k. Lets just suppose how far it will going to fall may be more 1-2k not more than that. I am new in this forum, but still I used to saw bitcoin rise since last winter.
What i think is, its the best time to invest coz every day there is some new news related  to crypto world. Every now and then there are some positive news from some well known and high ranking people. This i think is sufficient enough to prove in nearby future BTC price is going to rise once again.
