Halving will be only in 2020. Therefore, I believe that during the 2019 you should not expect anything at all)
when was last halfing? do not think that bullrun depends on halfing. but i agree that bull will not come in 2019.
of course it depends
take a look at this chart ->
statistics are here to show the past trends, but we can make some predictions on that
cause, after the halvings, there were some bull runs and massive dumps, now we are (i hope) at the bottom of the bear, and waiting for a new halving/bull run
so?) it is just growing. you can use picture of buggs banny and this chart will show how market grows with years. just new people enter in cryptocurrecy world. plus whales.
So this time will be a great time to buy bitcoin according to that picture. But you don't have to use all of your money and depends on bitcoin only because we don't know when the price can increase so you need to think about what will you need to do after you get that bitcoin. It is better to use the money you can afford so you can do many things with the rest of your money, and maybe you can find another business in your real life.
