Investing in an ICO is not a good option as one needs to be cautious while investing with them. The best option to grow your altcoins is to hold good and profitable coins. Also, it's smart to invest in more than a few coins and not just spend the savings in one coin.
We could also trade and hold simultaneously, which means trade some of the coins and hold some.  

Bitcoin has more than tripled in 2019, and it seems like a bullish market. Also, BTC is expected to hit $20,000 by the end of this year. This could be because BTC is gaining popularity day by day, and its users are increasing in number globally.
Even now, if you ask some of the people which cryptocurrency to invest in, they’d say Bitcoin without any second thought.
With this rising dominance, it is expected for altcoins to die soon as there is very less amount of altcoins available in the market right now. Bitcoin has always dominated the market flow, and it currently holds almost 70% of the market cap.
And, I think BTC will maintain this position for the future to come.

Although cryptocurrencies are aiming traditional payments methods, it has yet not managed to take over the old system. While the digital currencies have generated significant interest, its adoption rate is low, and government support for them is nonexistent.
And, not until the government recognizes BTC as the legitimate currency, it might take a while before we see its adoption. Also, there are many factors that need to be changed in bitcoin for it to take over the traditional system.   
 

Agreed. Even if the government bans bitcoin in the country, I don’t think its people would stop using or trading bitcoin. Here cryptocurrencies are banned totally. But, it cannot stop people from trading it. Well, who doesn’t if one sees how profitable these can be.  
Also, yes, the decentralized nature of the bitcoin makes it impossible to ban.  But, we can face some problems in the mass adoption of cryptocurrencies.  
 

Cryptocurrencies are banned in my country, so I'd probably get jailed or fined for asking this. 

The best way to secure your bitcoins is to either use a hardware wallet or a multisignature wallet. Create a seed phrase, write it down, and keep it in a safe place.
Also, if you are storing the funds in a hardware wallet, don’t store all the coins in one device. Instead, distribute your funds into two wallets. But make sure your codes and passphrase are secure in case you lose your wallet.   

Bitcoin’s price will keep increasing regardless of all the obstacles it has placed in its way. 2019 has been bullish for the crypto and speculations are being made of it even touching the $20,000 mark by the beginning of 2020.  Even the Bank of China is promoting Bitcoin to its customers. Biggest of all, none of the world governments or its laws govern the virtual currency which will always be an advantage for it. 

I've used many forms for exchange in the past, most of which were average. Out of all those that I used the most suitable and trust worthy has been beaXchange.
They have most of the major crypto-currencies for trading and interestingly enough, they charge no fees for registering and to start trading. Good thing is, it's available on all platforms so I can use it on the mobile as well.
Their commission rate is the lowest I found on the market and it has saved me lot of money I usually agreed to give away on other platforms.
I highly recommend beaXchange (beaXchange.com)

There are many exchanges including Binance, Coinbase, Coinmama and Bittrex. You can buy from any of these trusted exchanges. Also, there is one more exchange I've been hearing about is beaXchange (https://www.beaxchange.com/).
I've never used it personally but have heard a few good thing about it.

The very first step to protect your crypto is to store them in hardware wallets, paper wallets, or cold storages.

Keep these tips in mind as well:

• Keep your information private and avoid public WiFi networks that are an easy target for hackers.
• Always use strong passwords and add 2-factor authentication for all of your accounts.
• Store your cryptocurrency on multiple wallets.
• Always use a password manager, so you don’t use an old password.
• Do not post your email address, home address, or phone number on social media.
• Keep your antivirus up-to-date to avoid downloading malware.
• Don’t forget to backup your wallet periodically.
• For cold storage wallets and backup wallets recovery seed at home, keep them in a fireproof safe.  

There is no denying that beaXchange is the best exchange for crypto trading. It has the most volume of all cryptocurrency exchanges; is available in multiple languages, and also comes with a mobile app.

And, I must say that review is very comprehensive and does justice to all the features of Binance. With the same structure, I think that you can review Bittrex (https://bittrex.com/), beAxchange (https://www.beaxchange.com/) or perhaps Cryptopia (https://www.cryptopia.co.nz/)

Most people new to the world of speculation and trading start defining trends with indicators and signals from the past. They don’t take the time to learn why trends begin, how trends move through time, and how they end.

Technical analysis is often used to show how easy it is to be successful in hindsight; however, the reality, for most, is different when they attempt to use a TA system in real time.

There is no such thing as “the best bitcoin wallet.” But undoubtedly, hardware wallets are a great option. But if you don’t want a hardware wallet, you can consider paper wallets. In the paper wallet, you print out a sheet of paper with your private and public keys, which is stored in the form of QR code. Also, these wallets are not connected to the internet that protects it from hacker theft. 

Also, you can refer to this guide here “Choosing the right digital wallet to store your cryptocurrency.” It will surely help you.
