I held off, read up and then failed to buy anything earlier in the year. If I had...
I'm in now but only very recently. Moral of the story is if you believe in BTC as a future currency which has many years of life in it then buy in at whatever investment level you can and don't overthink it. I'm sure you know (but many dont still), just buy fractions of a BTC that fit your budget.
On the other hand if it's just because BTC is on a price peak/upward trend and you're just playing to speculate the market then hold out and wait until it hits a level that suits before buying in.
