Converting should not be in the option now, as we see the market isn't good state now so better hold, once you convert it there's no turning back your investment already lose.
The market isn't so good for altcoins and if someone converted his bitcoins for altcoins, he's now regreting.
Why would you sell your precious bitcoins for altcoins that are just depending to btc?
You can buy altcoins if you want but don't exchange it for something that has lower value.
Its ok to convert your shitcoins to bitcoin, this can prevent you from losing big money. But I do suggest to hold more good altcoins like ETH because it will pump again just like the trend today. Dont ever exchange your good coins into shit coins.
