Even in an old project, if we are hesitant or in doubt, it will be better to not do it. Investing is only best if we are confident. Researching helps us better to decide if we will consider the project or not but we must always prepare for any possibility if we pick a new project because some of them are only good at the beginning and at the middle but later on, they can fail.
We can apply the famous rule in finance which is to invest only the money that you can afford to lose. There are people whom I know who only treat new projects as a short term investment but I think they will only re invest on the project again if they think the project is stable and doesn't have a questionable future.
If you want to invest in crypto, you better find more information about the project so you can find out if the project is worthy of your investment. Of course, there is no guarantee that the old project will produce better results than the new project and to find out, we have to find out for ourselves. We also don't need to spend a lot of money to invest in one project and it's better to spread the money over many potential projects so that our profits can be bigger. Apart from that, this also prevents losses in one project if the project cannot develop properly because we still have investments in other projects.
Investing only the money we can afford is the main thing that we should be aware of because we will not lose all the money and can still choose other projects with more potential for improvement.
Those doubts should be a sign to not invest in that project, I remember that when I first read about bitcoin and how it worked I was marveled about how something so incredible could exist.
And while I cannot claim that I understood everything about bitcoin back in my newbie days, I immediately knew that bitcoin was an opportunity like no other I have ever seen, but if your first reaction towards a project is to have doubts about it then you know there is something wrong with it.
It's better to look for other projects if we are in doubt about choosing one project. I have experienced that but I tried to continue to invest in the project but it turned out that the project really couldn't improve and eventually disappeared. Fortunately, I don't use big money and only small money so my losses are not too big and I can profit from other projects.
For bitcoin, it is our biggest opportunity to invest so we should focus on accumulating more bitcoins. And while we are still buying bitcoin at the current price, we have to use it well so we don't miss it to get big profits later.
