I think the team behind that new coin should have the goals instead of the investors.

I got huge profits from old coins. For the new ones, I did not invest and if I would have, then there would have incurred huge losses.

Bitcoin is the only coin you need to buy. Forget about any shitcoin that comes up, bitcoin will always be resilient to changes in market. You can buy it at lower price and sell it at high price therefore making a lot of easy cash without thinking much. But coming to altcoins you need to do research before you invest, bail out before it crashes and so on.
