As a means of maintaining value, in the present bitcoin has been defeated. On 12/17/17 btc=$19379 and today 7/11/18 btc=$6345. A drop of $13034 or $501/week. I bailed when I looked at the slope and the previous 2 weeks saw 5.05%/week drop. Right now the the $501/week average amounts to 2.57%/week.
But compare the price today the price from past years. Even if you take the price exactly 1 year ago, which is not even a good buying point, you still have a gain from $2000 to $6400.
The problem with these kind of analysis is it compares ATH, which was a ridiculous pump, to the current price. While completely disregarding the bigger picture.
Anyone who bought at maybe around $10000 and didn't sell at the peak made a rookie mistake of joining in the hype. The consequence is that they have to wait longer than they would've expected, and that's completely acceptable.
