We are in the same situation like in 2015 when the price of BTC dumped to 90% and just stay side away, but after that the price rally to more than 3000% , so no reason to left this market and just keep holding strong and we will be get big reward later.
Any altcoin really can not take off (and whether it is necessary to take off at all?),but bitcoin is not a simple patient.namely bitcoin in the long run will be very expensive.Do not look at the charts see what is happening around bitcoin.As for me, the background is very positive.
It is time and our internal trust about bitcoin which is making it even more stronger and more effective than ever, now a day bitcoin is not very high it as under correction but profit making strategy and its potential is higher enough to get out of this dip and bearish market faster, so including bitcoin no crypto currency will ever take off from market as now mankind has recognized the importance of crypto currency.
