Do you choose to hold or sell? I choose to continue holding.
If Bitcoin falls 20% so obviously I will buy some coin. I like to hold Bitcoin. I think Bitcoin will hit $10000 at the end of this year. Then I will sell some coin and I will wait for the next dump.
Yap it is just a one time to buy btc when price drops. Actually not just bitcoin but some altcoin for keepsake. And sometimes having a day job , i could really miss important news on coins in general. I would just go home and notice how the prices moves in just a span or 8 hours. It is not impossible for bitcoin to attain such and if the surge continues, people who hesitated to invest in early days would regret it.
