Bitcoin Dump - The Worst Thing
When BTC dumps, all other coins also dump, it is worst thing because even if bitcoin dumps, then it should not effect the other cryptocurrency price value in BTC. i,e when BTC dumps the price value of altcoins is also drops while it should increase because btc downs. When people will realize it that it is not in their benefit?
You can separate the strong coins from the rest of the pack then. If everything is burning but some hold their levels it means they are either more worthy or bottomed out and you have clearly lower risk speculating on them.
