my questions are:
-When is it the right time to invest in bitcon?
-How can one start planning?
-How do you follow up your bitcoin investment and other businesses?
-What are the assurance that you are ready?
I think the only important question on your list of questions is how to know the right time to invest in bitcoin, the rest of other questions are completely unnecessary - sorry to say.
And in terms of knowing the right time to invest in bitcoin, I will say the same thing I've always said when I come across questions like this, and that is that, there is no right or wrong time to invest in bitcoin as long as we are already here today looking forward to tomorrow., the only right time I can say - to invest in bitcoin was yesterday, but since yesterday is past and no way to go back into it, another right time is today and now, and this is because, in terms of price, the market movement is unpredictable, you might want to for price to drop but instead, it end up going up.
So for me, I think the best time to invest in bitcoin in exactly the time you have your funds ready, and have made up your mind in invest that funds in bitcoin, you may decide to use DCA or any other strategy, but what is most important is that, you have taken the decision and are already investing.
