Dont worry if there comes a panic selling because it only means that there are more coins available to the market and more coins for the bigs to buy. Panic selling and the price drops? There's even more panic buying because they'll be thinking that the price would go up.
Panic selling is an opportunity and we should not worry for the panic selling because we all know what to do and that is not to do the panic selling and just wait for the dips to come up and buy at the dips and keep it in a safe bitcoin wallet for long term investing and that is how you will become a successful investor because you are thinking out of the box.
Panic selling gives loss to bitcoin as well as investor and those who are newbies are the panic sellers because they take seriously to every news against bitcoin whether it is rumor or not and when it is confirmed that it was rumor they start regretting so everyone should ignore suck kind of news and manage his nerves so that he can earn through bitcoin rather than facing loss.
