I think you're hinting around about ethereum when a huge sell order caused price to drop. I don't know about bitconnect. I haven't invested yet, but have tried. My virus software (malware bytes ) keeps closing the site down. Plus I lost about $1600 on bitlake. Still can't decide if I should shutdown malware bytes long enough to get account going. Bitconnect seems too good to be true, but man are people making money.
