BTC or ETH

after being in the crypto scene for a while, the safest is to invest into bitcoin. When there is a bear market some of the alts lose 20x their value from all time high. and even eth loses a lot of value. but bitcoin even tho it still loses a lot of value it holds it much stronger than all the otehr crypos. But if you were to invest in one of them i would just do both eth and btc
