Choosing the right investment opportunity is what people have failed to do and end up getting financially screwed when the chosen investment fails and their money goes down the drain.
It’s always best to spread out your investments and not to dwell on just one source. But what people mainly fail to do whenever choosing through available investments options is their thorough research on their viability.
There are some good alt coins that has shown some promise and made some profit for some people who were willing to take the risk. We shouldn’t also forget that no matter how profitable an investment may seem to be, there’s always a possibility of it failing.
All investments have a risk of failure, but because the movement depends on the product and demand in the market, it is better to invest entirely in Bitcoin while the remaining money you use can be used for altcoins, which are in the first 10 lists on coinmarketcap, so you don't need to worry about choosing. Because it is certain that if you are in the top 10, then the altcoin is good enough to keep for a long time, and the most important thing is to always record all the transactions you make to monitor assets and what percentage of profit you have obtained.
