So why not just buy gold, silver, euros, yen, yuan, AUD, CAD, or CHF? None of those has fluctuated much this year against each other.
Bitcoin has lost close to 50% over short periods THIS YEAR (Apr 30-May 14)! How did that preserve anyone's wealth?
Gold was up about 4% over that period roughly implying the USD was down about 4%. Other major currencies stayed roughly in balance with each other.
Conclusion: Major currencies are much more stable than bitcoin and therefore much better for preservation of wealth!
All of the currencies you have mentioned have declined in terms of purchasing power over time, although yes, their rate of decline as been rather "stable".
Gold and silver - yes these were traditionally used as preservations of wealth against currency devaluations in the analogue world. And indeed, they may still have their place, but in the digital world, Bitcoin is replacing the role that gold traditionally played.
As for volatility, we discussed that earlier. Bitcoin is a great example of how volatility should not be confused with potential for long term value. (Same applies with stocks by the way).
One week - up 1.67%
One month - up 31.2%
Year to date - up 117.8%
Year on year - up 363.48%
Two years - up 584.92%
Three years - up 849.82%
Five years - up 8381.40%
The key of course is to hodl. But yes, if you have the wrong composure, or fail to take a long term view, then you could well be the one who sells on dips (when if anything you should in fact be buying!). So investor education from the outset in this space is important.
Not many people are advocating putting all their net worth into Bitcoin. Rather, it is most sensibly viewed simply as an additional asset class to allocate towards (both for diversification purposes, and as a hedge/insurance against a range of future scenarios that could have a devastating impact on traditional assets and stores of wealth).
The OP is only putting a small portion of his wealth into BTC and ETH, and is "averaging in"
by allocating 1% of his income monthly. To me this is a sensible way for anyone new to Bitcoin to allocate and diversify into this asset class. Such an approach also helps reduce any concerns about volatility (which may help for those with a weaker "hodling" constitution. Good on him I say!
