Don't be affected with those FUD'ers: bitcoin will go down because of banning of ads on facebook, google and now twitter etc. etc,. Think of it those big companies they won't all in all block crypto's because they are also gaining profit to it, they are not dumb that they don't have bitcoin and altcoins in there pockets, and they are also using this dips because this is a huge opportunity to gain more. look at what happend to ethereum its on in its huge dips thats why buy and hold
. Don't be a weak investor.
I agree that there is now no need to sell coins when prices in the market are declining. But I also can assume that these bans of advertising related to crypto-currencies can be influenced by some countries, and not by the companies themselves.
