As the client and I want the custody to remain in a CEX in case everything goes to hell, therefore the hacking risk will not be haunting me.
Are you really sure that you want to hold such a big amount in CEXE's? I wouldn't sleep well but each on their own.
In my humble opinion, this isn't the best time to start investing in the market, I would wait for the bear market.
Having said that, And considering that you still want to start such a venture I would allocate the portfolio as follows:
40% BTC
30% ETH
20% Stables
10% Alts/NFT's/ rest.
Probably even more in stables though.
Few more things to consider:
If He/She/ They don't agree with all those terms beforehand be ready to say bye-bye.
Trust me, it's not worth it if you're doing it for pennies. Make things clear before starting.
All of this, of course, my 2 hivies.
GL!
