Diversify. That will be the next step for a successful investors. You really need to find another way to put your money on different basket. It could be on stocks or gold so that you will have multiple sources of income. Of course, you will still be investing on Bitcoin in the long term, and then get the profit and then scatter it across. And then back to 0 again, during the bear market, accumulate as much as you can and then sell at the right time. Same with your diversification, get money if you profit and then re-invest somewhere. My regret is that on gold, I should have invest years ago and I could have profited by now. Oh well, another expensive lessons for everyone.
You have pointed out really important idea in investing means putting your money in different things. I will also say that it is important for people who are good in investing to not put all their money in just one place. It is good idea to spread money into different types of investments like stocks or gold or in other altcoins too.
Your experience with gold is really helpful and showing that how important it is to look at more than just one type of investment and think about what different markets might do in long time.
At end you gave next idea of investing that is putting money in different things actively buying and selling Bitcoin depending on market and then using profits to invest in other places is really good plan for making money in long run and staying financially strong.
