Don't worry about whether Bitcoin is perfected yet.
It is just time for it to go back to ATHs because there are finally major upgrades on the way. Buy rumor, then sell the news. Meaning you are buying the fact that crypto is progressing and not sell because of the realization it isn't perfect yet. The problems of crypto will get worked out over time via competition from altcoins and Bitcoin. Right now, the smart (early mover) money is selling altcoins to buy Bitcoin in anticipation of the big move up which appears to probably be finally upon us.
Then at ATHs next year, they will be selling BTC to buy into altcoins for the next wave of 10 - 100X gains on the serious altcoins.
Learn how the smart money is getting rich in crypto (trading between BTC and altcoins, and buying serious altcoin ICOs and holding for the 10X price rise). You need to first toss out your emotions and learn to think rationally.
Overall good calls.. for me the uptrend is clear. We have been on the way up since january 2015, where me and some others called an unique opportunity to get in at such low prices (BTC traded as low as 150ish during that crash). Of course and always ruling out potential "hacks" (which btw, over time seem to be less damaging to bitcoin because it absorbs the impact better), the uptrend is still there and there are positive stuff to look forward with the up and coming software upgrades. The problem of mining persists, but I am also positive about us seeing the situation improve:

As banning carrying gold around becomes the norm and more people get aware on bitcoin, we will see an huge surge in marketcap.
Im also all about getting rich through altcoins during BTC corrections.. problem is, I see less and less "serious altcoins" popping. It seems to me like everything has been tried before, and it has always failed to get any traction. Do you see any ICO worth investing at? Most ICOs end up at lower prices than they sell for. Once it hits the market, instadumps always happen, then it's when you should actually consider buying, in hopes for a post-ICO pump that may or not happen, so it's a total gamble. Even "really serious" coins like ETH can end up in an endless mess and never get anywhere after they peak.
I feel like getting rich with an altcoin requires very precise movements and situations... like the ETH/ETC mess was a good one. Or when new concepts are introduced like back in the day with NXT (I think it was the first POS) or Blackcoin (afaik it was the birth of "hybrid mining" and people got hyped) + all that marketing they invested at, or when there's a big project like MAID that has not gotten any press, then it goes viral, explodes in price, and unfortunately keeps stagnating for ages again.. there's always a big risk of buying something that all it does is stagnate unless you sell it at a moderate price increase (if you get too greedy, you will miss the pump). It sucks since you get way less profits, but it's worse to end up with a bag of useless coins.
Then there's Litecoin and the "silver" psychological factor (which for me is it has the "original altcoin" aura about it too)... you may think right now by looking at the all time graph, it has bottomed and it's a good bet to buy a decent amount for a long term strategy of waiting for a BTC disturbance and hoping for another LTC pump, but you may see it stagnate in slow motion for many more months... and who knows. We have not seen it yet, but we may start seeing "famous" coins getting delisted if they stagnate coupled with no software updates.
I just don't see anything that makes me want to move a single BTC from my wallet. All horses have been already beaten. The smart contracts one, the "anonymous coins" one with the XMR viral news and the ZEC mess, MAID as far as I know still fails to deliver what they promised, then you have ETH with the constant hard forks, the STEEM thing which got pumped by famous crypto people and we all know what happened.. I see no good investment opportunities, not even for pump and dumping with a reason other than pure luck (for example 1Credit whatever that is, just got pumped the fuck out out of nowhere)
