When I invest in an ICO and it goes on the exchanges at way below ICO price...

However there are few projects after the listing they leave the project and not developing any future projects that is the time i think you will cut your losses.

That's a good point, it is essential to keep track on progress being made, including team changes and key targets on the road map. I've seen a few collapse along the way and lost a bit in the process, but it's all a learning curve. Have already learned to be a lot more careful when selecting, mainly because I am not investing too much at the moment. Taking a bit of a break during this bear market and trying to build up some cash to get back in later.

but there is also a phase where you can buy the token on Presale, and more bonuses when private sale.
so it might be better for you to hold the token if you buy it at ICO
