It's not enough having an investment plan, knowing the right choice to make for every investment defines the investor better. Take for example jumping on every new coin we find on reputable exchange might not be enough guarantee that coin will do well in the future.
I think people jump from one coin to another to seek for better profits and most often than not, the people who does this are short term holders, they check the gems and most liquid coin on the market and because of the demand, they make easily 10% to 20% from their investment than waiting an entire months and year to see the fruit of your investment.
Some coin might have good Supply but low liquidity, some might have high market capitalisation but very poor volatility. Although it's hard to predict the accuracy of a coin performance in the near future this why it is always advised to stick to the known which is BTC.
I like bitcoin but because I like bitcoin doesn't mean that others will love bitcoin and you know why? That's because people see more plenty opportunity outside bitcoin. You can hold bitcoin for a year and get 100% profit but gold altcoin in 24 hours and get 2x of bitcoin profits, you see the logic? However, altcoins are dangerous and can make you become nothing in less than 24 hours of you pick to invest in the wrong coin but people don't just care about the risk, they care more about tbe potential than the risk and hence the reason why they prefer altcoins than bitcoin.
Another option is to spread ones portfolio amongst different coins but ensuring the have a greater percentage in projects with a visible future. It is better to win small and lose less than lose more and win less
There is no strategy of investment that beat this, whether it's crypto or anything outside crypto, it's expected of you to diversify your portfolio so that when one is not working or have some challenges, the other will be doing the work and giving you the profits, that's the only way to win from investment.
