You can't really go against the grain of the market when you working on short to mid term. no reason to stay in one place when there's consistent % gains denominated in BTC to be had across the whole market.
Ah ok. I am not interested in that (as reasoned in the OP). I have enough gains in BTC. I am not really angry if MRO is tanking and I know full well how many dollars of new investment is needed each day to retain the valuation.
As with BTC, it does not matter what the price is. What matters is how many % of the coin you own, if the technology is sound and has a potential to break out. MRO was the first coin with interesting technology and fair launch. That's why I hold approx the same % as I hold BTC.
I mentioned this in ToF, so let it be known here also that I like MRO very much at 0.002, I like it at 0.004, but would not buy over 0.010. Going to 0.020 in the immediate future is a sell zone with an intention to buy back at 0.010 or less.
Of course, I only focus on the percentage ownership/total supply too. I think it's the most logical approach
The thing is, not to state the obvious because I''m sure you're very aware; If you believe MRO/BTC going to 0.002 when it's currently 0.004 if you sell at 0.004 and manage to buy back in at avg 0.002 you've increasing your holdings 100%. In such a fickle and volatile markets where these kinds of falls and rises are inevitable, where is the sense in not doing this? unless you really do not have the time and already sitting on a such a nice pile of BTC to not warrant bothering riding the waves when you believe it's going to go sky high regardless; (such as this fellow)
In a stable market, price is declining 50% of the time, so that's not an issue. As for being blown out of the water, being the in leading position in contention for 10% of global GDP still makes me wet.
It's nice to have this optimism. MRO can be quite valuable from his projections

I sold at ~0.0062 because it was coming down. I've no doubts it will rise above todays 0.0046 in future but it's also coming down to below 0.004 (likely within the week). So short term trader like myself with a little patience will almost double holdings compared with buying and holding.
