Safest way to buy and store bitcoin

Hello

Im kinda newbie here

I currently hold about 0.2 btc at robinhood.

Im hoping to buy more btc when it crashes to under 12k

My 2 questions are

1) do u think its safe to buy btc thru robinhood?

2) if not where should i buy and how do i store it in a cold wallet? (I heard cold wallet is the safest form of storage)

Thank you in advance
