If someone just listened to you and managed to buy at $6,700 now he's on profit.
The current price now as I type this reply it's now at $6,900 so there's a $200 within a single day so that's a very sweet profit. But this isn't the end of those profit because the big recovery is about to come.
Buy now, sell after 6 months.
LOL. Thats as if he's buying 1 btc, also ignoring the current buy/sell price on exchange plus the interest. I think he would not profit that much as you said.
Who knows if he's going to buy 1 bitcoin. What's good on this is that you can buy with fractions and even it's 1
BTC he still got profit.
How can you be sure that price will recover within 6 months and not decrease? These are highly uncertain times and with news about Bitcoin(crypto) regulation by govts, there's no telling how things will turn out.
Is the whole situation after 6 months is still doomed? there's nothing wrong to be optimistic and I'm being positive that it will be the recover time for bitcoin during that time.
No one really knows what will happen in the future as I'm giving an example buy now sell after 6 months or even more when you had profit already.
