I realy want to buy Bitcoin i have 5000$ give good idea plz
A 5000$ is more than enough to buy bitcoin. It is also a good time to buy bitcoin because the price of bitcoin is very low that it already drops it's price below to $7000. There will be a huge chance that you can double your profit, if bitcoin will start to increase it's price next year of 2020 that a lot of people are expecting that bitcoin will reach to $20,000 again.
if the research says to buy then we can use the results of the research to buy it, so every time there is a profitable opportunity it is better to start investing. and I think if only using the words of the people then the investment can not go according to plan
I agree, if you see that bitcoin value is going up and in a good condition buy as much as you can. But you must know and accept whatever happen. If the value of bitcoin go down after you buy learn to wait and keep holding until it pump again.
