Diversify your position
Don't limit yourself only to bitcoin. The world of cryptocurrencies has much more to offer. Learn about other cryptocurrencies such as Litecoin and Ethereum. Those currencies might be much more profitable for you.
Take advantage of CFDs
You don't really need to buy cryptocurrencies in order to trade. Cryptocurrencies has value just like stocks, commodities and indices. Many brokers has an option to make a deposit in standard currency but trade in cryptocurrencies.
Make your research before you trade and familiarize yourself with the tools you are using as well as the cryptocurrency market. Start in small amounts and increase only when you start making profit.
Cryptocurrency is a 24/7 Global Market
he market never sleeps. Since you do, consider automating your investing strategy using limit orders, stops, or even APIS (AKA "trading bots").
Altcoins and Bitcoin often do the opposite of each other
it is not rare to see Bitcoin go down while alts go up (and vice versa). This is because everyone who has alts has Bitcoin, so they tend to move out of Bitcoin when it goes down and move into alts.
Don’t share your private keys or passwords
You have to share your public address to receive crypto coins, but never share your private keys or passwords with anyone. If you can avoid being online when you enter your private keys and passwords, that is even better.
Realize that Bitcoin could get supplanted by another altcoin over time
For now, Bitcoin is both king and queen. This won’t necessarily be true in the future. You can be right about crypto, but wrong about coin choice.
