Maybe around $240, it's one year ago when i bought many bitcoins. Because i know well about bitcoin is around 2015 when the price is $200++ per bitcoin.
That is still big, mate I once bought some 7 bitcoins when the price was around 30-40$ , but my bad I sold them when the price got to some 100$ , because I thought that its enough to get more than double. Also i didnt knew that time that BTC will once cross 1000$ !
