Yes this is a good time to buy altcoin and invest in altcoin, although the market is no longer friendly due to some issues from other countries. Altcoin will still be the best crypto currency with a lot of communities so that people who support this too much, good development. It all guarantees that the value of this coin will surely rise, so do not be afraid to buy and hold this coin.

It all depends on what kind of wallet you use. I choose MetaMask and cold wallets. Also recently released MEWconnect application with a high level of security. I have not yet had a single case of hacking.

As of now, more and more users are getting the hang of sitting by their computers all day and they get paid millions through the help of bitcoins. What they earn is more than what they had in real life which makes life convenient and easier.

On the other hand, bitcoins are really helpful and accessible to everybody or to a group of individuals and they just click and their wallets get full. But what if, sometime in the future, bitcoins become more private and unaccessible? Will that cause a problem? What could've happened to us who were engaged in it first rather than the newbies to come?

Hi,

Every exchange adding a new btc, eth, token address on the exchange website.
I think they need some private key to set the transaction on this websites.

So is this private key stored in a normal database?
And is this safe?

Do you guys think tron trx is the ethereum killer? Justin Sun claims that his token is better than ethereum. What are your thoughts about this?

Dogecoin has been my favorite alt coin for quite a long time. It serves as a good cryptocurrency for tipping others, as well as being a fun and inexpensive medium of exchange.

However, I'm worried what might happen to Dogecoin in the future, since it has been quite some time that no new version of the QT wallet has been mentioned, neither some innovation to keep it going for the long term.

It would become ideal for Dogecoin to add SegWit to its code, and gain traction if it gains acceptance from the miners. Then, if it manages to become the first cryptocurrency to accept the scalable solution, it could rise in popularity once more (not to mention that transaction will be near instantaneous).

Nevertheless, Dogecoin is a great cryptocurrency being inexpensive and relatively stable, making it a great way to tip others or send micropayments faster than BTC at a fraction of the cost.

Looking forward to your opinion. 

ETC was just listed and trading on coinbase. Comparing with NEO, which one is better for holding?
