If you've seen my previous article in regards of HODL-ing.
Let us cut to the chase in understanding it firstly, in short; staking is the bread and butter for established coins and tokens whilst HODL-ing is more effective for pre-launched or budding crypto.
I prefer to avoid spending too much time in technical analyses or reading the news but have nothing against those that does it or enthusiastic about their favorite coins or tokens via it. There are those that are very involved I see them as the backbone of a crypto and the mere participants to profit off such as myself. When the 2 is in balance, a coin or token has more potential to grow.
The Established

Note that I say "established" because for late-comers HODL-ing would relies heavily on luck and the coin's or token's public-relation-reputation which is undoubtedly requires a bit more browsing and a lot of reading of news and charts regarding a token or coin you wish to invest in.
Established coins and tokens are those that have reached pseudo-maturity or maturity or a level of stability where the price is mostly ranging. It doesn't mean they won't rise in value or decline but the timeframe for it is slower than it was launched initially and more solid which makes them a reliable option in buying and selling merchandises in real life markets or popular choice for swapping.
We're in luck however because many established coins and tokens often offer staking options in many different reliable platforms online which are free to access with simple sign-ups. Some platforms however may have regional restrictions so ensure that you check your region's status.
Staking in easy to understand manner; is a more proactive use of your investment as you provide liquidity or to validify blocks of your chosen coin or token to gain more of it. It is putting your money at work for you while also affected by the natural rise and decline of price.
Your state of mind while focusing on staking compared to HODL-ing

The state of mind in staking however pays little attention to price fluctuation as opposed to when you're HODL-ing since you will likely compound interests or constantly swap profits for other uses.
The thought of the compound interests will compensate the loss from price declination and profit off more from price inclination is one of the major differences.

Finally, if you understand and combine the application of HODL-ing and staking which are like convenient tools at your disposals.
You will start to juggle more coins and tokens in a more efficient and flexible manner maximizing profits while minimizing losses and fees.
Remember that in truth, there is no fast way to gain lots of money in a short time unless you're very lucky. But if you relies on luck, that is really no different than gambling in any work you do. All works require a set level of skills, persistence, knowledge and a steady state of mind in regards of it. Especially when you are your own employer. Having luck however, is not a bad thing. As I always believe "Why not have both skill and luck?".
