If those relevant historical events went completely unnoticed by the "experts", I think none of them has real bases to present themselves these days announcing that bitcoin will reach this or that price by the end of the year.
I would rather say Never Trust them forever and not only for 100% because they are only talk shit about prices,these gives false expectations for investors instead of gaining because they mislead people loss is what we earn rather than profit.so better find your own research about coins and not to buy their stupid advices about value of each coins
