Girlfriend wants to invest, but I don't know shit about fuck.

So, the good news first. My girlfriend is ready to invest into crypto (\pats myself in the back)*. She has fiat ready, sitting in an exchange. Now she's looking for a good opportunity to buy in.

She is asking me for advice, and the thing is, I'm no expert either. It's just my second month into the cryptoverse, and I think that makes me kind of a newbie. I only know the basics - DCA and HODL if you believe in the coin, buy the dip, take profits if you want to etc etc.

I can ask her to buy the next dip, but I don't want her losing money. She'll invest more for long term returns, but only if she does not lose money in the next few days/weeks/months after investing. She, just like you and I, sees crypto as a medium for parabolic growth, and I want her to buy in at the right time.

So tell me what I can ask her to do. Which coins, and most importantly, WHEN?

EDIT - Since I am desperate for a good answer to this, I'll tip a couple moons to the ones I find helpful.
