The common valuation for most ICO's is right around 5 million softcap and 15 hardcap. Most ICO's these days rarely get above a consistent 50k+ volume daily, unless the team has some sort of experience backing them, let's face it, most have no clue on how to maintain and grow a crypto.
The best thing to do as a trader/investor, is sit and wait till the coin hits the markets. More often than not, you'll be able to snag some discounted tokens/coins. There are rare cases (mostly with the tokens coming out of asia atm), that they outperform their ICO prices. But, the days of making returns on ANY ICO investment is long gone, especially in this bear market and within the foreseeable future.
The good ICO's that are highly profitable, you are very likely to miss, due to mass garbage. There's nothing you really can do about this, unless you spend hours researching per day (full-time job), or just are pretty lucky.
I absolutely agree, too much risks on participating on ICO's. Many ICO's price right now is dumped, I think the right thing to do is wait them to list on exchange especially decentralised exchange,it gives you more tokens than participating in ICO and it gives lesser risks compared when you buy on ICO.And I suggest that you buy existing coins with a lot of potential on the market and hodl it for a year.
