Re: Privacy with sending BTC from differents addresses but same wallet
Yes. The solution is to generate multiple addresses on the exchange.
Take note not all exchange have option to generate multiple addresses and they could change it due to "security" reason.
And for IP I need a VPN and I'm think I'm good for it ! It will be enough caution for me 
Be really careful when using VPN since few exchange disallow their user to use VPN or see it as suspicious activity.
Hiding through VPN is not 100% that you can protect your self not to leak any details/information from your device or PC.
Most of the websites right now are smart they can able to retrieve some information from your PC even you use VPN which I think the information they retrieve can be still used to determine if the user uses their service with the same information even you use different IPs.
