On this I will say there is no guarantee too that you will be able to make profits from holding too, because it’s basically a form of trading or rather prediction too but only has less risk compare to the future trading.

Trading is different from investing. In investing, we are actively trading or flipping coins to gain a profit but in investing, we are only holding our assets and wait for the bull market to earn a profit. Investing still has some elements of trading once an investor sells their assets for profit. Sometimes, they can just choose to trade it with other assets that are also high in value to make things easy for them.
Both acts are unpredictable but if you have stock a good knowledge about them, you will know what assets to pick and what actions to do to make you more successful with them. Future trading is another variation of a simple trading or also known as spot trading. It's more advanced but a spot trading alone is still more riskier than investing. Manipulations are not only for altcoins or on it's specific type but it happens too in BTC. Their effects for it can only be less though because the supply of BTC is already well distributed and other factors can be a reason for it. Technical analysis is an important part of trading. It's not just what you call existing for a trend.
