That's true and not wrong at all, but I think it's more suitable for you to say to newbies who have just entered the world of crypto or have just entered the market to buy whatever they want without considering which one is best. Because I'm quite sure that currently there are still many newbies who make mistakes in choosing which coin is the best to invest in so that the mistakes they have made can at least be reduced when someone gives them advice like this by considering major coins such as Bitcoin and try to ignore any altcoin to no longer invest in it, unless only to trade it in the short term.
I will appreciate your decision that you did not choose the wrong coin at the beginning of your investment. A new investor's main problem is to choose the right coin. In the beginning an investor does not understand that which coin will be right for him or which coin to invest in will keep his money safe as well as give him a chance to profit. I learned about cryptocurrency through Bitcoin so I had no chance of choosing any other coin to invest in. At the time when I first started investing, I understood Bitcoin as an investment and I have always been very interested in investing in Bitcoin.
In the beginning I started my investment journey with a relatively small amount of money and gradually as the idea about investment grew and when I got different ideas about holding the investment I planned to hold my investment for a long time. I got enough benefit by holding my investment for long time and now I believe in always holding my investment for long term.
Those who are new investors should choose a good coin first at the beginning. When an investor is able to select a good coin early on, he will make a 50% correct investment decision.
