There is not currently any BTC in the wallet minus a few hundred satoshis:
Well 172,000 satoshis or about $14 dollars at today's price. The transaction history doesn't seem to suggest that the address is regularly swept as many sites do, so that's likely to be all that is there.
You're wrong here: OP says "Ill give a 1/5 of the amount to the one who is able to assist not much I think in amount of 0.08BTC or 0.1 BTC". That leads me to believe there's 0.4 to 0.5 BTC in his account.
On 2017-08-12 he deposited 0.01953317 BTC
On 2017-08-11 he deposited 0.48 BTC, and at the same day he also deposited 0.49411783 BTC.
Now if I assume this is an exchange, it could very well be OP has 0.5 BTC left in his account on the exchange. It doesn't matter how much this address holds, that's irrelevant when it's an exchange.
I think mocacinno is on to something here:
If you manage to identify one of these 237.000 addresses, you'll find the owner of the wallet... You can use google, or the searchfunction of this forum... with so many addresses, there is a big chance of finding a match.
I assume most of those 237.000 addresses are customer's deposit addresses. If you find a customer, you find the exchange!
But, mrpunxs, isn't it easier if you think really hard which services you used in August this year? Is it an exchange or a casino? There aren't that many large sites, so it shouldn't be too difficult to find it. If you see their website, do you think you'll recognize it?
And, next question, how will you reclaim access after you've found the website? Do you think you can recover your account from your email address, or do you still know a password to log in?
