It is better you invest low amount of money on bitcoin right now. If your salary is $400 monthly, you can be investing like $20 on bitcoin which is 5% of your monthly income . The price is high already but there is tendency that the price might go up. If you can be patient, wait until the next bull market begins after the coming bear market to invest more. I may not be absolutely right but that is my opinion.
Now lot's of people are on the rush to kick start their investment, the price was very low then and just few were able to take on the opportunity, we can consider this moment not too brilliant to begin the purchase depending on how long the profits are expected to be returned but basically on the long run, now is neither not the best nor the worst position to enter the market, we are current half way into the bull run and more prices are expected to be witnessed, investing now but just with little decent amount is better than doing nothing.
