And remember , investing in Bitcoin is risky and could lose some or all of your investment. Always do your research, set clear goals, and never invest more than you can afford to lose.
You can tell that to shitcoins but as for Bitcoin there will always be ROI for you but it might not come as soon as expected which is why holding BTC is always required to attain that... Buying for just a short period of time might not meet your expectation when the time laps so you might even end up below your entry point.
