Picking a Cryptocurrency exchange is crucial to start trading, this is where you buy and sell cryptocurrencies. Before you pick a cryptocurrency exchange, the first thing you need to do is look fore the companies safety and security protocols. Gemini is a good one to choose, they have great safety protocols and even available in Hawaiʻi.
Knowing what you are investing in is essential. This will give you better understand of what you are investing in and some reinsurance to where you are putting your money into.
With investing in Cryptocurrency, the more money you put in the more you gain but it also goes the other way. So only invest the money you are willing to lose, so the risk will not be high.
When you follow the news and current events on Cryptocurrencies, it gives you an idea of how well certain currencies are doing. With the understanding you have after following the news, you can then make rational decisions.
With investing, you are going to fail. It happens to the best of us, but don't be scared of failure, learn from it and try again.
