When we lost much money with crypto investment we always think crypto and bitcoin is bullshit, but if always got profit with bitcoin we say bitcoin is the best investment way for increase and get much profit, we have control and ready when some time we lost money with bitcoin or altcoin investment,
There can be loss in the value at one time and can be rise another time. In addition, the market rise and fall also matters a lot and I think you should be optimistic rather than staying pessimistic.
