Absolutely no, we all knew the risk in investing in cryptocurrency so we cannot called it safe haven when we invest in bitcoin. Though I fully believe in bitcoin and that it will become mainstream in the future, I still think there are risk on investing on it. There is still a chance that bitcoin will not do good in the future. But if I will to choose, bitcoin or altcoins then obviously I will go with bitcoin. As per investing in cryptocurrency bitcoin is the safe haven and not an altcoins or stablecoins.
