There are many ways to trade your bitcoins. For you what is the best?
Well, I guess the better and good way I think is use our bitcoin in the exchange platform to buy some other altcoins which is a legit one then its up for the traders if they're gonna trade it for a short or long terms to get profit in the long run.

I am sorry in advance but I dont think so its sagacious to buy altcoins for bitcoins. Its good to do trading at famous exchanges with bitcoins but buying altcoins or any other coin is not a good move. Personally I feel that bitcoins are an epic asset. One should keep them for as much time as possible. When prices are high, and then convert them to fiat.
And why do you think its a bad idea to buy altcoins? Do you got any proof that bitcoin is a guarateed one? This crypto world is just on its beginning stage thats why to take
advantage on all of its opportunities as much as possible you need to be open mined about it and the things that surrounds it because it'll constantly change, the rise of the other
cryptocurrencies was also a part of it. well a person who knows about that won't say what you said but not everyone who knows had been a trader but at least they recognized its
potential--that its profitable. trading bitcoin to altcoin or vice versa has been profitable for most people as well as me--probably the best source of my crypto income as of now.
