Yea multi year trends and exponential scales is not something I look at daily, weekly or anything besides reading other peoples conclusions.    I'm not against it exactly but I dont feel any weight when I try to use it myself, I cant really estimate for some profit personally.   Except that its reasonable at times to be long term bullish,  it can pay to just be Satoshis own sunbeam in the gloom because we are placed for a rise.
   Multi year charts need deep pockets because it might just take a year to play out, I do recommend consider the idea to buying regularly or dollar cost averaging.   Thats less about trading then most speculative bets people take, alot of faith and patience is required.   My pockets have holes in them  

 I say this about gold also, its a ten year asset.  People moan but it might fall for a year or more and have nothing wrong.    A few commodities are like this, its hard to capture the rapid rise possible.   Standard business cycle is about 6 years I think, thats the time frame required to consider alot of investment.   To establish a mine takes a decade easily, few years less perhaps for surface mining coal but the epic surprise to me is maybe BTC is one of these movers with giants footsteps to it.  
   I still believe 2021 and beyond will be bigger then 2020 in sum total.
