Yes, because the Bitcoin network, for years, has proven to be stable and safe. Besides that, the Bitcoin ecosystem is getting better every day.
yes it is a fact and i also buying it because bitcoin is trading just above 600$ so its mean that the price of bitcoin has yet so much potential to reach to a next high level, it is also expected that the price of bitcoin will easily cross 1000$ level in near future therefore i am still buying bitcoins.
As long as we continue to support bitcoin and we do not lose our hope once we see a crisis we will always achieve that amount, remember that we have already hit that price in the past so we can still do it again.
