..Just buy and hold bitcoin. Perform DCA in and DCA out. With your spare cash, put it toward innovative small-cap projects. The future is privacy, in my opinion.
That's how it often happens, after selling bitcoin for good money, we rush to buy "innovative projects" with this money and as a result we lose what we earned. If you do not use margin trading, then the correct solution is to wait until the BTC price go down again and you can buy bitcoin at the lowest price.
