Everything has pros and cons. But for bitcoin it really doesn't matter as bitcoin is really not dependent on these advertisements like adsense or any other which pops in between your browsing content similar to BitConnect. Though all crap ICOs are being published through such advertisements as that the way they fool people. So rather never buy that coin which just pops in between the page.
Nice article. Keep sharing. Upvoted. Cheers!!!
