First of all, don’t try to time the market. You will never time it right.
Second, what you are looking for is called “technical analysis”. That is based on the theory that all the information you need to analyze a stock or crypto token is in the market data (price, volume, etc.), and by analyzing the market data over time you may be able to see a signal as to when to make a market move. There are lots of resources available online to learn the basics.
And finally, let’s say you read up on this, figure out some of your own good signals, and start to trade based on them. There are professional trading firms who do all that, algorithmically, much faster than you can. You may make money, but it will always be after they do.
Still want to do it? Good luck!
This varies by state. In my state, my oldest gained access to their UTMA when they turned 18, but I am told I will still have my access until they turn 25, unless one of us explicitly revokes my access.
A UGMA/UTMA is basically a vehicle to gift money to a child, and then optionally invest it on their behalf, while having any gains on that money accrue to the child for tax purposes. Since most children don’t have much earned income, this will often result in them owing zero taxes on any unearned income on the account (unless there is more than $1350 of unearned income – read up on the “kiddie tax” if the income exceeds that).
OTOH a 529 is not a gift at all, until it is paid out. The money is technically still “owned” by the giver, they just have to name a beneficiary when they make an account. So any gains in a 529 don’t count towards the kid’s income at all, and if they are spent on educational expenses for the beneficiary they are not taxed on the other end either.
And once a year you can change the 529 beneficiary. So someone with a large 529 who finds that the beneficiary gets a scholarship (or doesn’t go to college) can change the beneficiary to someone else – even themselves.
