In the first case, I have secured my initial investment in the long term, so I won't need to worry about it, but it also won't make much more for me.
In the second case, the potential for gains is much higher, but I still risk losing my initial investment. I don't need the money now, but I would feel sorry about it.
For your first case, are you satisfied with your profit? Have you taken enough risk and now want to just reap profits without risking anything? Then go ahead. Take off your initial capital and invest rest of your profits. Choose coins that are well established and forget about them. Check them back after years and enjoy whatever you made!
For your second case, can you afford to lose? If you can, then forget about your "first option" and just invest. In both case, if you invest in well known coins, in the long run you will make profit!
