RetireJapan

Thank you. But when does that happen?

I read the retire wiki and I am still confused.

Current account
残りNISA成長投資枠（2024年）1,800,562円

I own Monnex 8698 Bought at 720円
If I sell at 802円 today.
I make 7,400円

What happens to this number if anything? 残りNISA成長投資枠（2024年）1,800,562円

I maxed out my daughter`s JNR Nisa last year and I have another kid on the way.
I wish to put around half of her Otoshidama into the stock market - she will have it all when shes 18.

What do you suggest is the best account/ service to use?
