You are aiming for almost a 150% APR with your capital, which is extremely risky. At that point, you are no longer investing but rather gambling and hoping things go well. Cryptocurrencies, compared to fiat-based investments, can be a good option if you are seeking high returns, but you should not expect to achieve such high margins if you approach it rationally. I work in the Bitcoin mining industry, and currently both my clients and I generate around 20–30% annual returns based on the current BTC price, which could increase significantly if Bitcoin goes up. While this still involves the risks of any investment, it is far more stable and higher than what banks or traditional investments offer. I recommend mining as a way to generate consistent returns without exposing your capital to unnecessary risk.
