All we know that bitcoin already hit more than $15000 last 2017 so there is a big possibilities that it may hit more that $15000 again. But no one knows when and how much will bitcoin will increase but the best thing that we need to do is have more patience and invest to hold more bitcoin and wait for the halving and bullrun.
I agree with you jazmuzika217 because demand and supply is a very big factor. Bitcoin is mother of cryptocurrencies and it touched more than $19500 in past. Add more if we have to buy any other crypto like altcoin we need btc specially in my county if I have btc i can buy other crypto I can't buy with fiat or credit or debit cards due to the restrictions by the government and still in most of countries bitcoin isn't regulated therefore bitcoin's price will be increase after halving.
