I suggest not to do it. Converting your bitcoin to ethereum is a bad idea because these two coins are highly stable coin in the market and worth holding. If you have enough money in your pocket why not buying another investment like ethereum? And if you dont have enough money, better to stay in bitcoin because it will give you profit.
Why not mate? Bitcoin and etherium are similar good coin and we can make much money from them. And now etherium has lower price which we can take the advantage from this. When the price low, we will be easier to double our profit like in etherium.
