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.
We can't force someone to choose the type of crypto they want to invest in, it's all their right and their choice is the best for themselves in the future, everyone has their own principles and goals in the future, it's all a choice.
But in the few years of experience I have been involved in the crypto market, with investment choices I have become fed up with types of crypto that are not popular in the market and in people's opinion, some of which are dead and have problems, that is a risk for each of us in investment choices, for this reason, currently I only dare to invest in two types of crypto, if we talk about investing in Bitcoin and Ethereum, maybe it is better for me than others, that's just my experience, the point is: everyone has different choices and views.
