I see that since you created the topic on August 12, there have been many answers that have been given by members here, for example suggestions given by:@log file.

However, you did not answer any of the topics that you wanted to ask, whether you are already using the platform or not.
I judge you are not serious in asking.
As additional information: Topic: What site to buy BTC fast?, for you, for sure you have to tell the members here from which country you live, to make it easier for other members to provide answers for you the fastest Bitcoin buying platform.
