iam also a bit nervous at the present, as iam a long term holder since 2013 and i missed the train of the highest peak to sell. now the dilemma is at aprox 8-9k$ usd
Just curious, how much you bought your coins at that time? I bet not even in $1k, so you can still earn if you sell at the current value of $11k if what you're saying is true that you are a btc hodler since 2013.
Nevertheless if you want to have a huge gain then continue to hodl because the price of btc is driven by the market demand. If there's less supply then the price will increase again.
