I tried to download Memorandum but I could not . after using VPN and changing my IP I was able to do that . I am not that expert in Bitcoin but I think I got the picture and it is an amazing opportunity for investors. just wanted to mention if we are talking about equal opportunities and also if one of the Bitcoin philosophy is to be independent from government( the rebel characteristics of Bitcoin players), we should consider these little things too and don't let sanction and other stuff effect the Bitcoin community . by the way I am from Iran .
