We are currently in a worrying and unpredictable scenario.
Well, there are several variables that need to be analyzed, because with the war between Russia vs Ukraine, cases of COVID increasing and inflation all over the world, this can interfere with the values of cryptocurrencies and video cards.
These variables are worse than the beginning of Covid when BTC dumped and them started the road to ATH, all these events together create a bad enviroment for all of us, but I think if the war ends, at least some money will start to move again and the world will start again to have some optmism, and then end of covid and pandemic situation will slowly get us to a btter place again
But to answer the question of OP, I survived the bear market of 2018
I was a miner in 2017 to 2018 and I saw the crash, I didn't had a decent plan and at the crash I had a lot of coins, a bag holder
After the crash I started to think better, and never sell any coin mined, I sold my cards due to my electricity costs, I had BTC and ETH, I put on cold wallets and waited.
In 2020 I saw some opportunity to mine again, I bought some cards and started
At ATH I was able to sell some coins, not all, but now I have cash to survive for some time
I know some things are easy to say or repeated a lot of time here, but it's true and can help in a bear market
1 - If you have BTC, don't sell anything in a bear market, unless you need to buy food to survive
2 - Stay only with coins you believe it's prepared to survive for a long time, for example ETH last time, like BNB now
3 - If your electricity is cheap, you can continue to mine, but let's say you have 10 cards, you can sell 5 and stay with 5, you will be prepared for both scenarios
4 - If you have spare money, or the cash of your sold cards, you can start to DCA, buy some BTC every week
Eventually prices will rise again, and you'll have coins to sell and profit, but if you sell in a bear market it will be hard to profit in a bull market, you will not have coins.
