The only safe haven in cryptocurrency is the stable coin like USDT, I personally purchased more Bitcoin few days ago because I still believe that the value would increase before long and I'm already in profit as at now. My safe haven in this space is with Bitcoin and USDT.
USDT is the safest shelter for all investors because this coin never changes its value. When the market starts to decline, holding USDT will give you lots of new investment opportunities and you will be lucky to buy many cheaper coins.
However, the crypto market is often a very unpredictable place, so consider buying and selling carefully because you may not always be able to make a profit here.
