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 ?
Why bother to do that? It will just give you more things to think in the long run. A headache for those who are really not familiar with the things related in crypto world.
First of all, what do you meant for a bitcoin crash? A price decrease only or bitcoin will become doomed? If for price decrease, then just let it go that way. In the long term, surely it will regained again it's pumping status so no worries here even the price decrease too much. If for a doomed thing, then putting money to other cryptocurrency is useless too since if bitcoin will becomed doomed, so on with the other alts.
