It is OK for BTC to touch $70,000 if it wants. That isn't a start of a bear market, it is simply trying 4o find its real book value at that level. All you have to do is readjust your portfolio, so as to accommodate this readjustment in prices and be patient enough for the accumulation phase during which we will see BTC price trade between $70,000 and $100,000 for about 5months. Then the great BULL of all times will come.
Trade responsibly.
