I think it's still not late to buy and hold BTC.
It's never too late to buy and hold Bitcoin.
With the price in the hundreds of dollars now, it might seem to some that they missed the chance to buy when it was in double digits, just as those who paid a few dollars per coin might have regretted missing the chance to buy them for pennies.
When bitcoins are worth tens of thousands of dollars, people will regret having missed the chance to buy them for only $630 each.
The important thing is not to panic and sell when the price drops. Hold on even if the price plummets to a small fraction of what they were once worth. It
will rise again.
