I think it's the right choice when you don't want high risk then you don't do it more because we know that investing in new projects must be prepared with the risk later, but if the right choice is on a popular coin then it's a real investment.
In the new project we must need deeper research on what they plan in the future, and even then we must be really sure if you want to invest it, if you are sure enough invest enough, put money there at all.
If you have studied the projects and see a perspective in it, then you can invest in it. But this should not be a large percentage of your deposit in order to reduce the risks. Moreover, if this is an investment at an early stage of project development, then the likelihood of getting a large profit increases significantly. Personally, I rarely invest in new projects, and if I invest then small amounts. I have not yet had the opportunity to buy tokens on sales.
If the timing is right, gaining a lot from new project is very possible. It's just that the risk is also high when participating in this kind of projects. The chance is slim as there are many scammers who are also good at hiding from the quality of good projects; you needed to work well and go deeper if you intend to invest with new project.
You need to research and dig a lot with new project, take your time and not to rush it will avoid you to lose a big chunk of your investment.
Sparing a small portion of your entire fund is also a good strategy, be very careful it's your hard earn money.
