If you want a coin with outsized potential returns on your investment, as I do, then Spectrecoin (XSPEC) fits the bill handily. Here's why:
As governments increasingly seek to regulate and track cryptocurrency trading and usage, demand for privacy and anonymity will be through the roof. Several anon coins have already borne out this demand by rising through the ranks in terms of market cap, faster than most alt coins.
There is one coin in particular which is still an undiscovered gem among anon coins: Spectrecoin (XSPEC). At 20 million initial supply + 5% annual increase (paid out to users in the form of staking rewards), Spectrecoin boasts a lower total supply than most. Between existing features and those currently under development, it stands as one of the most solid and cutting edge anon coins in existence.
It is currently still priced at under a dollar per coin, but I do
not expect that to remain the case much longer.
