There are many best crypto currency exchanges, but you need to understand just because of a better platform you will not start earning from there. I agree, we must need a reputed exchange at very first, still only with our skill we may start earning bitcoins.

Almost every exchange services are good and only fees differ, one thing you should consider is to avoid trading scam coins and if you lose doing so it's your own fault and not the exchange.
I just want to ask which site is the best to earn some bitcoin. These previous days, I lost my 5 BTC because of scammed coin. Hope you can help me.
Are you asking about good altcoin to invest into or best trading platform 
If you are asking about best altcoin to invest right now i am afraid that nobody could give you best answer as selecting any specific coin to invest into is really hard. However you can check each altcoin specially the devs and their experience behind the project, name of escrow if you are investing into any ICO, don't buy when price is pumping and at high price, don't sell when the coin you have bought is dumping hard.
Talking about good altcoin trading platform i prefer poloniex.com and bittrex.com
I got confused 
Your title is different from your details in your first post OP. So what's your real problem? There's a lot of crypto currency exchange there I don't know much of them, I am only familiar with their names. If you want to earn bitcoins for free, you can visit the services section. You can found a lot of services there but you need to have the required skills. But I think you need to rank up your position first, have patience.

Proof? What specific coin is that? You able to risk that amount in an altcoin trade then you didn't have a idea even just a basic of learning those risk involved in doing altcoin trades?
To minimize the risk about your latest unsuccesful investment, choose those altcoin exchanges that not listing shitcoins in their trading list like Poloniex, Ccex and Cex. But it will not give you an assurance that your investment on that exchange will be succesful. It's all in your hands to make your trading decision.
so its not about exchange from your word i think the problem is the coins
you should choose coins which have good reputation to traded
lots of dev coins scamming us with their new coins
on my side my fav exchange is bittrex or poloniex and the last for me is c-cex
