If you want to invest on bitcoin in long term then the current price is okay I think because it looks like the price never fall below $6000 so that little amount will not be a big problem in the future when the price will get too expensive.The downtrend may already over and we may see the price rise in the coming days so don't wait too long because the price can jump too faster while you are waiting.There was a slight upward movement in the bitcoin price yesterday so it looks like the perfect time to invest.
