In defense of coin market cap, it is not just data at one or two of the markets, it is also a massive amount of data at any (many), most? of the exchanges. You really have to look into it closely t see what it really says. I think coin market cap is probably just doing the best they can with what they get. Garbage in is garbage out. It is just many of the pump and dump coins and cons fake the data. They have bots artifically create whatever number and type of transactions they need to manufacture the volume of transactions they think would "look" good.

I mean just imagine for a minute Bitconnect is legitimate. And it only "sold" BCC tokens twice. One when a customer joined and then once when they left.

How many tokens would need to trade everyday?

See lets go with the 8,000 number of customers and assume they are all on a 6 month (180 day) investment plan and evenly spread out. 8,000 customers/180 days is 44 customers a day. If all of the customers had $1,400 each invested $61,000 of BCC would need to transact daily. If new customers joined at 8 am and old customers left at 11 am we would need two transaction. (If new customers bought directly from old customers we would only need one transaction.) That Means there would he $122,000 of BCC traded each day. Instead volume yesterday there is 15.4 million! This is flunking the smell test! All that volume is nonsense. If I told you I put 500 people in my car, you wouldn't believe me because any normal person knows a car holds about 6 and a clown car at the circus might hold 20! but there is no way it could hold 500. Well that is the kind of crazy numbers we are dealing with at the BCC volume. People who bought in to BCC aren't so good at basic math, so this is not a problem.
