When the market goes up, don't you think there was a reason why it went up? When the market shoot up, it's because of something good came as a news like the last news that broke this week when Bitcoin pump a little bit, the new CPI came out which indicated that predicted inflation was higher than the outcome which means that real inflation was low and that made market to flourish but market indicators is saying the market is due for correction and that's why the market is dumping.

Generally, market can't go up forever, it can't and it can't go down continuesly, there is always support and resistance where it settled and the continuation depends on what comes later, that's how the crypto market works. You should also bear in mind that the crypto market is volatile, the altcoins bleed the most and they also gives good profits, I guess the reason why you are seeing 1/3 of your assets is because you bought at the top.
