CoinSwitch supports most of the wallets. If your wallet address is recognized as invalid, there is always a reason: You confused Dash (DASH) with Dashcoin DSH). These are two different coins with two different amounts. You confused Factom (FCT) with Fantomcoin (FCN). Different currencies as well. Typo or character missing. Make sure that the address you specify matches the actual address of your wallet.
By 2016, several cryptocurrency exchanges operating in the European Union obtained licenses under the EU Payment Services Directive and the EU Electronic Money Directive.[21] The adequacy of such licenses for the operation of a cryptocurrency exchange has not been judicially tested. The European Council and the European Parliament announced that they will issue regulations to impose stricter rules targeting exchange platforms.
Depending on a jurisdiction you live in, once you’ve made a profit or a loss investing in cryptocurrencies, you might need to include it in your tax report. In terms of taxation, cryptocurrencies are treated very differently from country to country. In the US, the Internal Revenue Service ruled that Bitcoins and other digital currencies are to be taxed as property, not currency. For investors, this means that accrued long-term gains and losses from cryptocurrency trading are taxed at each investor’s applicable capital gains rate, which stands at a maximum of 15 percent.
TIP: The top coins by market cap are usually the best bets. Most of the top coins today were toward the top of the list back in 2015. There are a few coins high on the list today that you should be wary of, for example, Bitconnect. There are a few new ones, like the Bitcoin forks, Bitcoin Cash and Bitcoin Gold, that are new to the list. Meanwhile, there are a few that didn’t stand up to the test of time, like Peercoin. As a rule of thumb, historically speaking, the higher the coin is on the list, the more solid it is an investment over time.

There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as bitcoin result in high up-front costs to miners in the form of specialized hardware and software.[87] Cryptocurrency transactions are normally irreversible after a number of blocks confirm the transaction. Additionally, cryptocurrency private keys can be permanently lost from local storage due to malware, data loss or the destruction of the physical media. This prevents the cryptocurrency from being spent, resulting in its effective removal from the markets.[88]

The main concept of ICON is their idea of a “loopchain.” As stated in their whitepaper, a loopchain can be described as a “high-performance blockchain that can provide real-time transaction, which is based on enhanced Smart Contract.” Through ICON, participants will be able to connect to any blockchain without relying on the current centralized exchanges.
When it comes to other, less popular cryptocurrencies, the buying options aren’t as diverse. However, there are still numerous exchanges where you can acquire various crypto-coins for flat currencies or Bitcoins. Face-to-face trading is also a popular way of acquiring coins. Buying options depend on particular cryptocurrencies, their popularity as well as your location.
Cryptocurrencies' blockchains are secure, but other aspects of a cryptocurrency ecosystem are not immune to the threat of hacking. In Bitcoin's 10-year history, several online exchanges have been the subject of hacking and theft, sometimes with millions of dollars worth of 'coins' stolen. Still, many observers look at cryptocurrencies as hope that a currency can exist that preserves value, facilitates exchange, is more transportable than hard metals, and is outside the influence of central banks and governments.
In 1998, Wei Dai published a description of "b-money", characterized as an anonymous, distributed electronic cash system.[12] Shortly thereafter, Nick Szabo described bit gold.[13] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was described as an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.[citation needed]
