I had a bitcoin but withdrew like a month and half ago on coinbase to pay some college loans especially since the value kept dropping. Obviously not the case now, I have $4,000 in the bank, what can I do now to make the best of bitcoin or can you give me strategies as it starts rising again?
You have made the mistake and its very difficult to undo that mistake. I will not suggest you to go and buy bitcoin right now, as its going up and its not recommended to buy an upward going bitcoin. If you have 4k$ in bank then hold them in bank and wait for next bitcoin dip.
How about just spending half of the 4k like others have suggested? How about if it doesn't dip again for a long time or ever???
