I do not plan on selling bitcoins anytime soon unless something crazy happens on Aug 1st or soon after and the coin price dramatically increases....
Altcoins on the other hand, every day

something like when the price have reached $4,000 but then dropped to $400?
are you sure it could be a good and effective idea to make money?
i just think to always have a plan to hold bitcoin as much as i can for really really long time no matter what ,
i will just take that risk , for example keep saving your bitcoin 0.1 monthly for the next 30-50 years!
