2018 was a not great so far. It has not gave the prices which can give us profit. But I think this term is good for the coin uyers. In my opinion, ethereum, icon and stellar can be good picks for the rest of the year.

In my opinion, the simplest thing you can do is not to buy altcoins but to buy bitcoin and ethereum. They will surely grow in value 

The nodes in main network who want to add transactions for a zone would need to have all the zone files for previous block. The winning node adds current transactions, swarm defense signatures, network fork or merger points based on waiting transactions in current block for current zone, and awards for previous block. These details are verified by all other full-nodes or partial nodes for confirming the winner, and is an independently verifiable information sets.
The nodes in hyperlocal network who want to add transactions in hyperlocal dapp would need the main network state file and hyperlocal state file only. They don’t need hyperlocal zone files for previous block to add transactions, as any conflict will be referred to main network’s zone for resolution. Thus, the hyperlocal network would need to refresh themselves of 2 small files which would be less than a kilobyte, expectedly.
Repeating another historic assumptions like floppies, I expect that 1 kilobyte size for a network state file is large enough for all practical transactional needs and hyperlocal dapps extend that feature exponentially. Though time has proven all such assumptions are merely wrong in the vent of new innovations. Maybe in very long term, the main network would become conflict resolution media for hyperlocal dapps and hyperlocal dapps would carry all the functionalities. That way the main network will have highest performance. It requires a change of mindset from current notion of blockchains, and will take time for participants to realize the best usage of the network.
Blockchain has been one of the most amazing innovations since the Internet came into presence. Blockchain technology permits everyone to hold and make transactions as strangers but in a completely transparent manner. There is no mediator in between two person making the transaction, and the entire process becomes easier and cheaper.
The blockchain network comprises of nodes, i.e., distributed servers. All the nodes can accept and process the transaction. The nodes on the network share information about the candidate transaction. As much as the logic/tech part of it sounds confusing, the business models are so much easier to understand and are really impressive.
TIM is enterprise ready. Amongst many, few applications of TIM blockchain are discussed below:
Personal Blockchain: Fee Free subchains to be your personal blockchain - TIM can host 2^60 subchains which are protected by fee free challenger nodes. With same level of performance and security as TIM network, subchains can be your new email address or health record or roaming data storage like dropbox. There are a host of benefits where such a mailbox could be totally encrypted and free of any advertising or profiling your communications. It can be used for other services like one can pay for what you use for storage or bandwidth.

I would recommend that you buy the TDZ tokens. There are a lot of crypto market participants who will greatly welcome the opportunity to use a professional toolkit, which is based on mature market strategies and which gives regular people an easy way to enter the game.

Let me tell you about a little gem named Masari. Starting this month will be the first CN coin to have a mobile wallet, also new tech named uncle mining will be released in Q3. If you add that Cryptopia is coming soon and lead developer, which is briliant, also announced that he will work full time for development of the coin starting from September you will have an absolute winner with no better time to buy than on this bear market.

I think that we should not bet on alternative coins in 2018. This is very dangerous, and it is better to stick to a less risky strategy and invest in BTC.

The best altcoin to invest in 2018 is ethereum and some other stable altcoin like waves, neo, litecoin.
These coins are stable and they have great potential to yield profit if you hold on long term. They also have a large community and good management team.

Almost every altcoin from top 100 looks great, there are so many diffrent blockchain technolgies with many diffrent uses. So choose wisely and invest now, when price is low .

bitcoin FTW, even the bad market it can be m0re 6k in price. i guess it can be good again after accepting ETF
or if you wanna be safer, you can hold fiat n wait till market becomes good

in my opinion, ETH is one of the many altcoins recommended by investors. for those of you who want to play safe and do not cause much risk, ethereum can be your alternative. only me you have to play in a long-term investment. because ethereum is often slow in decreasing coin prices as well as being slow in raising prices
