I haven't so much knowledge about trading and haven't try trading yet...so which site will be profitable to me to take my first experience???
there is no site that make is "profitable for you". it is up to you to make profit. it is trading after all. you should "find" a good price to buy and then you should again "find" a good price to sell on your own.
the only thing you can get help from is the internet and social media. especially this forum, speculation section, announcement section and if you are into altcoin trading altcoin boards. to find opportunities to take advantage of.
thank U so much... I will benefit me...
