Well it was in 2011. The price back then was 20 usd and it was the top price at the moment.

I think a lot of us whould have done the same...

yes I agree. Bitcoin has grown a lot in the last year.
From $200 to a good standing for a month long at around $400.

I do not believe that if the price of bitcoin be $ 20 for 1 BTC, it would be very boring, maybe everyone will leave bitcoin, I think it is a number that is meaningless on the Internet 

The bitcoin will reach $20 when there is no consensus between the bitcoin community and there are hard forks of bitcoin and 2 bitcoin exist, one of them reach reach $20 or lower.

I read somewhere that the Core team will implement larger block size by April this year. So it will not be a big problem.

It's funny to see how some people don't read the thread and go straight into an ignorant reply, talking as if OP had posted this just yesterday. As for what had happened, back in 2011 when the price was at $20 people would have been inclined to sell. Imagine at this time if the price went up to $500, or $600. We would be inclined to sell our Bitcoins, just as much as OP. However, since the community now has developed, our views on Bitcoins are a bit more concrete and the number of people with bearish interests has dwindled since its time in 2011. Suffice to say, a smaller majority of people had high hopes back then, but of course, they weren't in the 1000s range.

Suppose the price does reach $1000 again. Would you sell, like OP? Or would you continue holding? If you had a lot of faith in Bitcoin, you would hold the coins, but I'm assuming that most would sell at least some of their coins. OP's decision wasn't that hard to understand.

thats true, bitcoin will start only growing and nothing else, i hope that it will be the future of all currencies

I think it depends on us, the users... Because we are usin it, its going high... If we totally stop using it, it may vanish...
It is just my opinion...a

Now that's what I call a blast from the past ... ! Bitcoin reached $20 in july 2011 but plummeted to below $3 in the final months of that year. During 2012, price rose very slowly from $4-6 in the first months to $13 in december. Who could have guessed back then that prices would absolutely go nuts in the following twelve months? Kinda puts the current bearish sentiment in a new light ...
