if you are a beginner then do a little purchase and do the purchase in stages consistently, I also make a bitcoin purchase for $ 5000, and you should be able to start from $ 1000 first.
Yes in very beginning it is important that start with a little amount, after getting some experience we can increase our investment. To me if a person do not have any experience in trading then he should buy bitcoin and hold it for a long time and i am sure that they will also get a very good profit. In fact bitcoin is comparatively more safe for investment.
