I don't have the balls to sell at this low and I'm keeping it for myself.
It doesn't take balls to sell when prices are plummeting. It takes balls to
not sell.
While your country is lacking of Bitcoin sellers, the whole world is definitely overflowing of it. The sell orders are inundating the market.
Seriously. I don't know what the situation is in Bangladesh other than what OP described, but right now it's definitely a buyer's market. Maybe if you're talking about a P2P exchange, it could be that no one wants to sell bitcoin at these depressed prices but no one should have any trouble getting ahold of bitcoin on a traditional exchange like Binance or Coinbase.
And hell yes, now is the time to make money with bitcoin. The key is to buy low, and I'd say it's trading pretty damn low. Even a monkey could make money in a week like this--assuming the monkey had money to invest, in which case he'd be in a better position than me since I'm broke. Figures.
