At the moment there is no international regulator body that can take cryptocurrency jurisdiction, regulations are each country obligation, like in the case for anti-money laundering and counter terrorist finance, some countries follow the recommendations emitted by FATF/GAFI (https://www.fatf-gafi.org/) adn its only a supervision job; and those who do not follow this recommendations or are consider dangerous, get into either a black list or a gray list, financial institutions may not do commerce with citizens from such countries.

Now, this regulations don work as an overseen job, it obeys to the supervision of transactions and transaction history, with limits applied to amounts for deposits and transfers. For instance, the total amount a person sends or receive in different money transfers or bank deposits. Also the names of the transaction holders are checked upon several lists provided by the FATF, if positive, transaction shall be denied.

This is the way exchanges are regulated, that's why, the greater the amount you want to transact, the more KYC information you have to provide. At the moment this is as far as regulation can go I believe.

I think it depends completely in the project planning and goals.

• ICO is the base and best option for those who do not intend to get their coin/token listed right away; for example, if some project runs a plan such as the EOS ICO, that was one year long and dynamic price.
• IEO offers a more comfortable option if the project looks to list right away and does not want to engage in KYC protocols, since the exchange will be doing such task.
• STO is only in the case of security token base projects, and it differs from the other two.

In my opinion, non is better than the other, they just serve different purposes.

Even though paid ads are very important for the people get their attention to whatever project, is the organic influencer the one that will give the necessary pump for the it, be it video or blog, after learning of a project, people will search for someone they already follow opinion before investing in a certain token.

Well, BTC is the trendsetter, therefore will always be the most import and loved cryptocurrency. Ethereum focus is on the DApps and follows a similar ideology. I personally believe they will coexist, probably in the near future ETH change its expects to also serve as a payment method for commerce, not only to pay the network.

Perhaps at some point, BTC will serve as a currency for "big" stuff, like buying a car or a house; and ETH will serve as the common currency for the day to day expense.

Time will tell...
