I agree with @onceuponatime and the only thing I would like to add to the rest of us the regular people is that in times like this the bitshares DEX can save a lot of the pain.

1. Don't be all in in crypto. I know it is difficult not to be all in and I also can't resist be all in crypto when we have a bull market, but keeping some bitusd, bitgold,biteur,bitcny for times like this is something we all need to consider more in the future

2. The history of cryptocurrencies have taught me so far that when we have so big % changes either up or down, usually a centralized exchange all of the sudden is "hacked" and people lose their money. Keep it safe and trade in bitshares DEX...

3. If you want to trade with leverage, just buy some bts and short bitassets into existence within the DEX. Not the best thing to do in a bear crypto market like now but definitely something to consider when the bulls are back. If you do decide to go down that road make sure you understand the risks and you are capable to maintain collaterilized your position.

4. When you are in a bear market and you don't know which crypto to buy just buy some bitshares and steem of course and HODL..Don't buy shitcoins but just buy something that has some utility.
