For example, if bitcoin is going to crash and I exchanged it into $1200 Ethereum lets say. And it goes down to $800 USD, will the Ethereum value go down?
Could you exchange your bitcoin into another currency to be protected from a crash?
I think Coins like Doge, LTC , USDCOIN all of these are 99.9% stable always in the same price, 0.01% prob that you are very very very unlucky and it drop when you buy but I don't think it will happen.
What do you think ?
If Bitcoin crash all altcoin will follow including Ethereum. The only safe way to prevent from losing is if you convert it to fiat and buy at low price. The only question is if you are aware when will be the next pump of bitcoin because if the price goes up and you didn't buy, you might end up losing too.
