At the end I just decided to continue with same pool, I just copy the ID and pasted on delegation by id.
I am thinking if it will be more profitable to delegate again every time we get a rewards, so the new rewards make more ADA as total amount and we potentialise composed interest.
Maybe I will try after every epoch.
What I don't understand yet is how I will cancel Delegation if I need to withdraw my ADA.
It says you can switch or cancel your Delegation, but I don't see the options, I just wonder because I will need to withdraw partially maybe next month.
Hopefully I will not need to withdraw if my other trades works well ...
Also I would like to complete a 100 K ADA to delegate, but nothing easy.
In the meantime, I have put a loan in ADA that's why I am contemplating to withdraw partially in case I don't adjust my monthly pay.
I hope I get lots of LEO and HIVE so I would not need to care about withdrawing some ADA ...
Have a nice investment!
