Before we invest $100 and expect to earn $100 in profit, we need to think that the currency we invest in should double in value. That is, now the price of Bitcoin is 30000 dollars. If you want to earn 100 dollars profit by investing 100 dollars, then the price of Bitcoin must exceed 60 thousand dollars. People who usually expect this have various negative comments about Bitcoin. We should not expect so much from crypto currency.
Please bitcoin doesn't need to be pressured in other to gain profits and for you to enjoy the investment the only alternative is to choose long term investment period maybe from 1 year to 10 years and enjoy the benefits of bitcoin instead of coming here to make unnecessary noise.
Investment is not something to impose on others. Maybe we can give some ideas to others about investing but we can never take responsibility for their money. And if there is profit or loss by investing, that investor will enjoy the full result of it, since we have no profit to impose investment on him, why should we impose investment on them.
