We could have seen that coming after Facebook banned crypto ads. In February regulators asked Google to band crypto ads too. Maybe we'll get anti-crypto ads next, just like the tabacco industry is forced to do.
Anti-crypto ads will be funny with taglines like:
1) Do not invest in crypto or you can become a millionaire
2) If you child starts investing in bitcoins in school, he may not need to go to college.
What disadvantages will they cover in those advertisements ?
