I have total $750 . i want to invest and i want to trade . so which trading platform so best for beginner ?
and can i make good profite per month with this amount ?
This is a tough question.. and also sort of a complicated one...You kind of have to break it down into two categories... which is just easier to place orders sell vs what has the ability to help you more as you learn how to trade and has more advanced tools..
First off if you are a new trader as in brand brand new.. welcome to the bigshow.. you definitely are making a good decision to start now over 2-3 years from now when mass adoption kicks in. The biggest problem you'll run into with such a small starting amount is the tendency to overtrade.. I found when I first started that was the case for me, and as my portfolio grew I didn't care so much about the day to day, which made it go much better, not worse.
So anyways, with that said... each exchange has flaws... but some are definitely better... but also some are more advanced than others, so I'll put them in two categories.
Noob Friendly:
GDAX (linked to coinbase) this exchange has low features.. but is easy to move into from Coinbase.. limit orders are free (which trains you not to always market order trade - very important since some exchanges will eat you up on market order fees (especially at only 750.00
Binance - Probably the easiest exchange to use. Charges low fees for Market and Limit orders so if you need to market order in a pinch, it won't cost you dearly... very high liquidity for coins on offer including BTC and ETH with tether pairs. The charts are awful, but other than charting and charting tools, this is the easiest for new traders to use.
Bittrex (with caveats) - The new interface is just bad... and it makes it more annoying to use. The orderbook for bids and asks allow for easier point and click pricing. This allows you to familiarize yourself with order flow more than most exchanges. Liquidity is decent (unless its a coin Binance also has.. Binance is the liquidity king for most alts). I used to be a big fan of this exchange, but the overhaul of the interface is just laughable.
Kucoin - Very similar to Binance in look and feel. This exchange has had some gems that have made some crazy gains (Dragonchain we love you!). You will eventually work your way here in your journey and its pretty simple to use.. very similar to Binance but with slightly better charting. I use it maybe 5-6% of the time, but you will most likely stumble upon here in your journeys.. and it's pretty decent.
More Advanced:
Etherdelta (Windows 3.1 anyone? Terrible design, and will be hard for new users to grasp.. one fat finger slip and you could accidently sell something at half price or buy something at 10X price because of a missing zero.. still there will be times to use this exchange for cheap coins that just hit the market but I wouldn't use this yet.
IDEX (Same as ether delta with slightly less annoying interface.. you will be here in your crypto trading career but don't start here.. plus speculative just out of ICO coins are not what you should be purchasing on your first few months.
Bitmex - The holy grail of all exchanges... HIGH liquidity.... MARGIN TRADING... This is where you will eventually end up (provided its legal in your country) when you've mastered trading. This is where dreams and (when homeless) are made of. Margin trade on up to 100X... once you have mastered all the others... you will find yourself here.. to find your fortune or to maybe leave with one shoe still left.
Bitfinex - Same as above but has Lending as well... you can lend out your bitcoin in periods of not trading to gain interest... its actually pretty good.. go on vacation for a couple of weeks and gain sometimes up to 1% a day on a stack you aren't using.
Some others that may be worth checking out.. but I don't think offer much of merit:
HitBTC
Cryptopia
Kraken
Whatever exchange you use, they all pretty much suck at charts.. so as you get more experienced, try to chart with Tradingview or Coinigy...seriously, its night and day in comparison.
Good luck, remember don't over trade with small stacks.. less is often more!
