How Do I Participate in an ICO?
In the early days, ICOs had a common problem: it was hard to spread the word about an ICO to the public.
You had to draw visitors to your private website, then convince them about the merits of your ICO.
Fortunately, a better solution has emerged. ICOs have been growing in popularity in recent years.
Today, a number of websites have sprung up to address the demand. The main platforms include:

Waves
ICONOMI
State of the Dapps  (based on Ethereum)
TokenMarket

These platforms give companies an easy way to advertise their ICOs –
just like how Kickstarter and Indiegogo give startups an easy way to advertise their crowdfunding projects.
Today, you can visit any of the sites listed above to learn about ICOs taking place – or to participate in an ICO yourself.
Some popular restrictions and regulations in the ICO world include:

Storing the contributions of members in an escrow wallet; in order to access the funds stored in the escrow wallet,
the owners need private keys.

One of those private keys is owned by a trusted third party with no involvement in the project development.

In other words, the funds of investors are protected by a neutral third party.

Companies may establish a legal framework between themselves and contributors, including a set of terms and conditions
for the ICO.

Companies will provide a great deal of transparency, in terms of their location, members, founders, executives,
business plan, roadmap, etc.

Ultimately, ICOs vary widely in terms of their trustworthiness, reputability, and future success.

It’s up to individual investors to spot ICO scams and protect their investments.
