I'm actually not worried right now, surprisingly enough. If Bitcoin crashes to the prices they dipped to in 2015 then I'll be buying them up by the bucketload :) - people see the downfall of the market as a time to sell, or hold. Me? I've learned through bitter experience of watching my 14 bitcoins go from £4000 to £1400, and if I still owned them now they've be worth $28000

When the market plummets I see dollar signs haha
