In my opinion the ICO investment will be good judgement for making a good return if the ICO has a solid potential in the market and has a unique product to meet some real life demand such as CellBlocks (cellblocks.io) ICO

We are there presently,  ethereum is dropping due to the crack of the sec on Ico which are springing up daily, well,  the sec is doing a great job in other to prevent it's citizens from getting scammed by unknown persons who just wakes up one morning writing a whitepaper that they cannot fulfil in other just to take money from innocent citizens and newbies.  The price will definitely come up back.

My strategy is to invest in projects with a real product that will be useful for the society. I think that these coins will give the best result in a few years. This strategy requires a lot of patience and effort. But in the end it will bring a very high reward.
