Investors in this industry, just like in the more traditional industries, need to rely on common sense and thorough due diligence when investing. Make sure the company has a thorough business plan, solid and experienced team, the business has a large enough market and potential audience and there’s a well-thought-out tech and product development strategy. Don’t invest in the ICOs on the basis of rating alone! Many ICO-rating websites have been slammed for getting paid to rate ICOs highly, and such ratings may not be reliable. Read the whitepaper, get to know the team, ask tough questions if you see any red flags and if you’re satisfied with the response, invest away.
