I am having an urge to invest all that I can in the potential project I like but it is also a good time to diversify the portfolio and trade some nice coins to gain short term profits.
What would you guys do if you were in such a situation ?
Do understand that none of the idea I'll share here are that of a financial advisor and they shouldn't be considered as an investment idea either. They're just ordinary ideas therefore you shouldn't based your decision on what I have said. Having said that, I understand you intend holding that coin for over 15years, that's a very long time and there would definitely be some ups and downs moment for the project.
Instead of locking up your funds right now, you can do the other which is trading some quick profits taking coins as we're in the bull run and everything is green. You can make some profit that'll contribute the the funds used in investing in that project if your choice.
Or probably instead of going all in now, you can fractions your capital, used some for investing and others for the trading, as you make more you reinvest in the project over time.
