According to other people way more knowledgeable than I am, the short answer is "no". The safest option is to put most, if not all, into USDT and then maybe use that to short BTC and ETH in a "bear market".....Then wait for the bottom and load up again to trade.
But as I said....I am still a noob and dont do this for a living....so others may have a more informed opinion / analysis on this.
