Bitcoin is currently playing between $38k to $48k so a good time to invest is when the market price is below $40k with the concept we can sell when the price breaks through $45k or more. according to some charts we see when the price starts to touch $46k the price will experience a correction again by 10 percent to 15 percent.
That was before but btc right now has found its new support it was 40k and it doesn't go below there. Waiting for the price to go below 40k can be hard now. If we want to buy we can start now since btc still at 40k. Don't wait before btc starts moving because this can be the last low that you can see but after this, btc price are now going to continue above 50k.
What your saying about the correction was true, I remember we are above 45k last time and then it falls back and never make it above 45k again. Let's hope history won't repeat itself because if there is one thing that everyone wants right now, that would be a bull run not correction.
