I originally invested in Tyhee on a recommendation (and my own DD) from Merv Burak, a CMT who publishes a newsletter with excerpts posted every week on Kitco.
Merv is bullish on Tyhee again, posting the following for subscribers this weekend:
Tyhee Development Corp. (V-TDC)
Time for TDC to start a turn around. After a 70% decline the odds may be in favor of an advance. The charts are not yet there but the momentum is almost ready to go positive while the moving average could turn upwards with very little additional price advance. The resistance offered by the year old down trend line may be overcome very soon. Most barriers would be broken once the price hits $0.45. Prior to that it is a greater risk and speculation.
