If you invested in every single ICO, including the crappy and scammy ones you would have seen a return on investment (ROI) of 1320%.
Think about that for a minute and really let it sink in...
If that statistic were true, it would be very encouraging to other people. But sadly the reality is that people get burned everyday joining ICOs that are actually shit.
I personally joined around 5 big ICOs thinking I would at least get my money back but was am sadly disappointed now that i'm at a -30% loss overall.
So that 5 big ICOs that you said, didn't guarantee that big ICOs can be profitable right ?
but let see, from where you get those information, ICO that you participate are the true big 5 ICOs, im just worried that you visit in the wrong ICOs review site.
Try the ICOs that become my signature, GL
