ERGO has very little liquidity. Not on many exchanges. Not on any of the large exchanges. Global daily trade volumes are usually only a couple hundred thousands of dollars. Not only is ERGO more prone to flash crashes, but it simply cannot support a large number of industrial (not speculative) miners since the liquidity to sell isn't there nor are there futures instruments to properly hedge.
The reality here is 99.9% of altcoins have no liquidity at all in the bear market, besides xmr and eth and in some cases btc, other coins have no usage whatsoever, reason coins once the bull market ends crash drastically, no usage, no hype, nothing, stay there until the next idiot grab money happens, so reason too coins crash 95 to 99% once the bull market is done for, because only ones selling will be miners to cover bills and investors know this and they dont rush buying coins.
So pay attention, that only coins with usage will fare better once all crashes, so coins like ergo, ravecoin, doge and others will crash so hard that will make you lose a lot of money overnight and will never regain that value until the next money grab idiot wave.
So want to keep holding coins and not lose much? think about long term? you will have to hold btc and only btc, now if you want to play the market then by all means keep all in usdt or usdc and then buy back once most altcoins crash 99%, buying now and holding long term is stupid, you must never hold crypto long term if you want to make most of it, buy and sell and time the market, do not be a stupid bagholder blaming others for your own decisions once this crashes to hehell, or when is hehell stage and it goes very fast and high, and you did not buy early, same thing, do not blame others you have not bought when it was cheap. Play both ways and be a winner.
