Is this a good time to go all in?

or at least to get involved more seriously? Recently I have listened to Michael Saylor and he said that we are at the point that resembles the beginning of gold rush in California and it's good time to be alive for bitcoin holders. Bear in mind fastly approaching halving, ETFs purchasing of bitcoin and a pattern of bitcoin increasing its value post-halving and never (well, almost) going below previous ATH. And currently we are conveniently sitting at previous ATH so it seems nowhere to go from here but up. Plus if you truly believe in an idea of bitcoin and the modernizing impact that it possesses what stops you from going all in?

Myself I have invested moderately over last two years, then had some doubts but now I consider more serious commitment.
