For me, IT is a good thing because they are really annoying to me. You can see that most of the cryptocurrency ads are about ICOs. ICOs somehow is not good in the crypto. Too many advertisements on Facebook can make other people misunderstand of what the cryptocurrency.
I am also not an enthusiast of ICOs. I don’t find them useful. Especially nowadays, we keep on learning about new projects and almost all of them are useless. There is a chance of being scammed too. Honestly, it is not like Mark is against cryptocurrencies. He himself is a tech guy. Few weeks ago, there was a news about him releasing his own crypto currency.
