Just Successfully WD from arbitragecoins.com.

Last time I try to WD from 30/11, they said the server are under Maintenance (upgrade 2FA security).
Successfully WD on 11/12.

My review about this site:

Plus:
1. Customer Support are good. They online almost 24hr/7.
2. Never got minus balance (due to good arbitrage bot).
3. Daily profit around 0,5% - 1% of your balance.

Minus :
1. Site detail are not shown: NO Contact Number, Address & Documentation (office photos).
2. Sometimes trading detail are coming late (almost a day without profit, but shown in next day).

Recomendation :
1. Invest on this site then forget it all (no other settings needed).
2. Invest minimum on 3-5 coins. Recomendation : BTC, BCH, LTC, ETH, ZEC & XMR.
3. Invest ammount are based on what you can lose (just in case site are going to SCAM).
4. Use your own money! And not urgent money! Witdrawal fees are $5.
