No one is late to the adoption. We have a good decade ahead of everyone else. Bitcoin is only 10 years old. It will be alive in another 10 years.

Best thing you can do now, is set aside a fixed dollar amount (or whatever fiat currency you have in your country), and buy every 2 weeks or every month. Just buy. Market buy. Buy order, it doesn't matter as long as it gets filled within the day.

Withdraw your bitcoins to your own wallet, where you control the private keys.

I keep my gold coins under the floor of my basement (see the movie, doh... )
