It's true bitcoin is really a good choice for investment. That is why it's very important to diversify your investment rather than putting them in a single asset can serve as a very important strategy for risk management .
 Yes I must agree with you that continuously investing is really a good choice. But note that every investor views bitcoin investment differently. For most persons it's a way of making profit, which is the main goal. But still there are some investors that view it as a passion, a hobby with that kind of mindset you can invest in bitcoin continuously With no panic. You see one thing about this bitcoin investment is that it's all about learning. And once something becomes a hobby to you in every way and anyway you will be motivated, to always finding new things to learn about it.
