Which coin have you held the longest?

Without selling and rebuying or even selling a small amount – and has it worked out for you and how long have you held? Do you think you would have been better moving on and are now effectively stuck or are you holding because you’re completely convinced of its future success?

Obviously if we could foresee the rises and falls we’d be madly trading coins back and forth and nothing would really be held onto (I think you’d take the hit on taxes if you were guaranteed to properly time the market), but are you happy with your decision overall to not sell or do you think you should have set a % target increase to sell at? Just wondering about the effectiveness of holding and the amount of faith people have in projects.
