Investing in top ranked altcoins is a safer strategy as those coins drop less then other coins in bears time and recover before all coins start rising but research is always required before making any investment Decision.
The unequivocal statement about the research and analysis of the market, which I fully support, does not need to save time on correct and long analysis of the project, if you save here, you will pay with your deposit.
Come on, nothing depends on projects and their products actually, the only thing that really matters is market. When we see a bullrun, even coins created ironically out of memes (DOGE) grow. And when we go down even good projects' investors suffer, so it almost doesn't matter WHAT you buy if you know WHEN to buy.
