Ethereum is associated with bitcoin, like all other coins, and if Bitcoin goes cheaper, Ethereum will also become cheaper. Therefore, it makes no sense to choose Ethereum instead of Bitcoin. If Bitcoin costs $ 300, then Ethereum will drop to $ 20-15. If you believe in crypto currency and Bitcoin then the best thing you can do for it is not to sell it and store it, but if you do not have it, now is a good time to buy it.
