I missed the bus in 2011…but

Hi all,

I am now ready to invest into crypto and I’d like to make some cash long term.

Let’s say I have 1000$ Cad.

Do I invest in one coin only or do I diversify?

My plan here is to buy, transfer into hardware wallet, leave in bank vault for next 3 years.

What would be my best moves and why?

I am total newb and need explanation I also don’t mind the 1000$,just gonna let it mature.

Thanks for the inputs all!
