The way this question is phrased is problematic.
Are pencils useful to criminals? They can be used to write down schemes for robbing banks, kidnapping letters, etc.
What about guns? Weapons give criminals an edge in committing crimes.
Of course, pencils and guns can be used against criminals as well. Most people would agree that it’s a good idea that weapons exist (even if you think that only the policy and military should have them) — otherwise, the strongest bullies could force their will on everyone else, and society would collapse.
So what you should really ask is – will Bitcoin lead to more crime or less?
Arguments for more crime:
- The quasi-anonymous nature of Bitcoin makes it very convenient for extortion payments, bribes, etc.
- Stealing Bitcoin can be easier than stealing cash given that it is portable, easy to transfer, the transactions are irreversible, etc.
Arguments for less crime:

The best way to estimate how many cryptocurrencies will survive the infancy period is to look at other markets.
For example, how many social networks survived the infancy period?
Facebook has 63% market share:
If you use a stricter definition of “social network” to mean “feed-based platforms based around personal profiles” Facebook has over 99.8% market share. Google+ and Diaspora are well under 1%.
What about Search Engines? Google has 87% market share.
What about Desktop Operating Systems? Windows has 82%.
What emerges from looking at these and other markets is that network effects lead to a dominant player, a secondary minor player, and about three competitors with marginal market share.
However, if you expand the definition of the market, the picture can change dramatically. For example, if you include mobile device in the “operating systems” market, Android is #1 at 41. Likewise, Facebook’s dominance varies from 60% to 99.8% based on how strictly you define “social network.”
Let’s apply these insights to cryptocurrencies:
A single dominant cryptocurrency is likely to emerge with 90%+ market share. Given the strong network effect of money and the probable lack of nation-state restrictions on adoption (unlike the USD), the dominance may be over 99%.
However, if we expand the market definition to “cryptographic assets” or “digital assets” then we need to include tokens and securities such as Ethereum and ERC20 tokens. This expanded definition may see the leader’s share drop to 60–70%.

I would argue the USA desperately needs open borders to avoid economic disaster.
1: There are 11 million ordinary, hard-working people willing to risk their lives and prison time to create a better life for their families.
2: There are 11 million American business owners who need hard-working non-professional workers desperately enough to break the law
3: US immigration law makes it nearly impossible for honest, hardworking non-professionals to become Americans legally.
Why are American businesses so desperate for workers that they are willing to break the law? There is a record number of unfilled positions in small businesses. America’s population is aging, and this will cause severe economic problems due to the unsustainable nature of our welfare programs.
The chief problem is the USA has been surviving on IOUs for decades, funding wars and welfare programs with debt. Trump’s budget means the welfare-warfare state is more unsustainable than ever, and within a decade, baby boomers will bankrupt social security and other programs.
The USA must have young, hard-working immigrants to avoid economic collapse. Illegal immigrants are even better since they pay into social security and Medicare/Medicaid taxes, but are ineligible to collect benefits.
The free movement of labor across borders is the single most beneficial variable in the US economy:
“According to the paper Economics and Emigration: Trillion-Dollar Bills on the Sidewalk? (2011) by Michael Clemens at the Center for Global Development, open borders could lead to a one-time boost in world GDP by about 50-150%.
Want a global economic boom? Open the borders
” typical workers in developing countries would see annual wages more than double, from an average of $8,903 today to $19,272 with open borders. That is, the typical worker in the third world would end up making about double the individual poverty line in the United States today. “
A world of free movement would be $78 trillion richer
