Of course it is worth continuing to invest in the crypto currency, because it has nothing to do with the bubble ...
If people will start worrying so they will not get any kind of benefit so it is good not to think too much just have patience, and wait to rise your income, if today price of bitcoin is low I am sure soon it will be high, never think negative about your investment with bitcoin as it makes higher profit, those who are saying it a bubble gona be regret soon.
