Bitcoin as a digital asset has taught me that patience is the key.
That applies to every type of investment, not only bitcoin. Warren Buffett, probably the best investor in history, built his wealth thanks to his huge patience, he never rushed into buying or selling stocks, he mainly holds stuff. The problem is that today many people like to sell some get rich scheme and other people actually fall for that, so there is this idea that you can become rich almost overnight and as soon as things require to wait, well, people don't want to wait.
Buying and selling is an investment approach, other than just buying and holding for a long time; either has its own risk. With the get rich scheme, you would be able to maximize the profit especially if you will know when is the perfect time to execute the action. On the other hand, just holding will still be profitable but never expect a really huge profit especially if capital isn't as big as the ideal. It will just save you from big stress. Indeed, this decision making is existing to all kind of investment. Both has the same output but not the amount. Bigger risk will always mean bigger profit, as its sole principle.
