Instagram Proxies

Hi.
I want to bot my account in Instagram but I need a good proxy I found some, my question is which I should buy and use?
I found:
proxy6 (Normal) & highproxies (Instagram proxy). (You can suggest better providers, but max 5$/Month)

Any experience with proxy6 or highproxies which is better?
Should I use IPv4 or IPv6 to bot in Instagram?
I have to use a German Proxy (Frankfurt am Main)

Try avoiding proxy providers which are being used by alot of people, go for IP4 over IP6.
On another note try to find some residential or 4g proxies, datacenter proxies have the like functionality blocked

Go for static residential proxies..They are costly but give you a peace of mind..You can run 4-5 accounts on each and non-US can be around $20 each
