Wait for the right time to invest and you will have the right timing to make profits. Don't rush in making money as crypto investment does not give profits overnight. It will take time especially if you are only here to buy and hold your coins, and just wait for a perfect price to sell.
However, stick to bitcoin if you prefer good returns and maybe include those solid altcoins so you can diversify your portfolio for future profits.
I believe that we should not be focusing on how to make a profit right away, we should be focusing on how we could better our lives in the long run. If we get into the trap of "I need to be rich right away" then we are never going to be rich, however if we consider how long it takes people to get rich then we could potentially do something good. Nobody got rich overnight, Elon Musk worths 300+ billion dollars now but he started working in 90's, same goes with Jeff Bezos who started Amazon before 2000 as well. Look at Warren Buffet, dude is 90+ years old and he amassed 100 billion dollars but it took him 7 decades to do that.However, stick to bitcoin if you prefer good returns and maybe include those solid altcoins so you can diversify your portfolio for future profits.
I am not saying that it should be taking that long for you, facebook started in 2004 and look how rich Mark became, and there are other people who got richer quickly but I would say a few years is definitely not enough. So plan ahead and plan slowly, make a goal for 5 years, 10 years, 20 years and finally 30 years, that should be enough for anyone to get rich if they do everything right and be patient.
