Do you have any proof or evidence of people blowing their trumpets about their earnings and what they've acquired in the cryptocurrency community,if you do i/everyone would love to see it..
I think people who do such(80%)are scammers who are either trying to entice you to "double" your bitcoin, or telling you of how they acquired so much interest from a particular investment,urging you to deposit to claim your rewards also,it occurs everyday on multiple telegram groups were a group of people pop in with a sort of deposit to claim,or send a particular amount of bitcoin and get double the amount,and others who are in the same trick with them start blowing trumpets of how it worked for them and how they had 4btc,but now it's 8,and all that, it's just simply crazy
No legit/real investor would come openly to let the whole world know about his/her earnings as it makes no sense and stands nothing to gain, other than being traced,robbed,scammed or killed.
