History says, no market goes in a straight line. It has a business cycle where ups and down of price is a general scenario. But Suddenly unnatural increase of price is not stable. Don't you think instant increase of bitcoin price from 30k to 65k was unnatural? So it is a general scenario of price falling. Besides some incidences like china's ban of bitcoin, Elon Musk's forbidden of car sell with bitcoin etc have helped to decrease the price. But I think it will recover soon. Market of 2018 is not the same of 2021. So it is not the effect of history. It is the  effect of business cycle. 

প্রকৃতপক্ষে দাম কমা বাড়া মার্কেটের একটি সাধারন অবস্থা। তবে বর্তমানে অসাভাবিকভাবে বিটকয়েনের দাম পড়ে যাচ্ছে। এর কয়েকটি কারন ইতোমধ্যে আমরা লক্ষ করেছি। ভারতে বিটকয়েন নিষিদ্ধের গুজব, ইলন মাস্কের বিটকয়েনের মাধ্যমে গাড়ী বিক্রয় বন্ধ ঘোষনা, চীনে বিটকয়েন নিষিদ্ধ ইত্যাদি। পাশাপাশি একটা কথা মনে রাখা দরকার। মার্কেট যখন খুব দ্রুত বাড়ে, তখন খুব দ্রুত কমারও সম্ভাবনা থাকে। আমরা দেখেছি কত দ্রুত বিটকয়েনের দাম ৩০কে থেকে ৬৫কে উঠেছিল। সুতরাং আবার যে কমে যাবে এটা তারই একটা প্রতিফল হতে পারে। মার্কেটের এই প্রভাব এখন সব কয়েন ও টোকেনর উপর পড়েছে। তবে ২০১৮ সালের মত হবে বলে আমি মনে করি না।  তাই আতঙ্কিত হওয়ার কিছুই নেই। আবার মার্কেট ঘুরে দাড়াবে এটাই আশা করছি।

Market is always uncertain. It can change positively or negatively any time. So real traders have different trading strategies. I think, using stop loss is one of the strategies. Our ultimate goal is to make profit from trade. So we have to try to avoid loss. I think, using stop loss is a very good idea in this case. Those who don't use this strategy can face uncertain loss.

Ether is the most favorite altcoin to me. It has occupied the second largest market share of the crypto world. Its acceptability in the world has largely increased tremendously after bitcoin. It is now being used in different fields. We see that its value has already increased more than our expectation. I think this value will highly increase again in the future. So I always like to hold  ethereum as much as possible.

Its a very interesting topic. BNB is the first cryptocurrency that I earned from a bounty project arranged by bounty ditective. It was a memorable day when I got my first bounty payment and BNB opened a new journey of my life because I first started my trade with BNB.

Everything is possible but it is a matter of time. Cryptos are gradually acquiring the world's market. More and more people are entering into the crypto world. Different countries are coming ahead to permit crypto transaction. But still many countries have prohibited cryptocurrency which is the main obligations for universal crypto transaction. Yet I hope, one day will really come when everything will be crypto.

Ups and down of price is the common scenario of every market. It is the best trading strategy to buy when price is low and sell when price is high. I am agree with your suggestion to buy some stable coins at this moment. Because price is in decreasing rate and I think it will go up very soon. Now it is the time to fill up the bag.
