Dont think any one singular of those is the "right one". Rather we have to combine #1 with #5 and from that we can make a solid gameplan. With how much you need to retire in mind that can help set goals and guide the
way you go about trading. This might make some players in the game super aggressive while making others calm and relaxed. I have seen both of these players in this industry and the only thing that is changed between
them is their mindset. Those two to me standout in terms of what we need to "win" this cryptogame
I agree with everything that OP said mostly, except in the third point:
3. Set up a portfolio with at least 50% in BTC, 30% in ETH/LTC and the rest in perhaps 3-5 other cryptos that you believe in and follow. Make sure to do your homework as the risk goes up exponentially as you move down the market cap ladder.
I wouldn't feel comfortable holding any crypto for 5 years other than bitcoin. These altcoins don't bring anything new and groundbreaking enough in my opinion, in order to consider them long term holds. Im sure some of the alts will deliver mad gains but I would stay at a safe 60% minimum BTC then 40% speculation with altcoins to try to find the get-rich-quick one that gives %100 gains in a span of 1-2 years.
