Neither.
Ask yourself if bitcoin is the currency of the future why is the guy who is selling to you parting with his? Especially for filthy fiat? You will be handing 30k to a miner that conjured units of nothing up from thin air because of an "algo".
The time to buy bitcoin was when the market cap was in the low millions, even at low hundreds of millions. Today fully mined supply puts the value at $10-12billion.
You will sleep better having enjoyed the money on something else. You know like something you may actually need and find enjoyment in. Bitcoin has ruined more lives then it has helped.
